Answer:
Homework is needed for students to practice the material they are learning. The more you practice each new concept, the better you get at it, and the faster you do it. By practicing a lot, you also end up memorizing the way to solve problems.
Factor the following trinomial completely, or state that the trinomial is prime.
3x^2+10xy + 8y^2
Answer:
(3x + 4y)(x + 2y)
Step-by-step explanation:
3x^2+ 10xy + 8y^2
All signs are positive, so we'll only look at positive factors of 3 and 8.
3 factors into 3 and 1.
8 factors into 4 and 2, and it also factors into 8 and 1.
I like to try closer factors in value, so I'll start with 4 and 2 for 8.
Try:
(3x + 2y)(x + 4y) = 3x^2 + 12xy + 2xy + 8y^2 = 3x^2 + 14xy + 8y^2
The middle term does not work. Switch 2y and 4y and try again.
Try:
(3x + 4y)(x + 2y) = 3x^2 + 6xy + 4xy + 8y^2 = 3x^2 + 10xy + 8y^2
It works.
Answer: (3x + 4y)(x + 2y)

The higher degree terms are going to grow much faster than the lower degree terms, so that is what we need to focus on
The highest degree terms here in the numerator and denominator are 8x^6 and 4x^2, so let's divide the two, and simplify to get our solution;
f(x) = (8x^6) / (4x^2)
= 2x^6 / x^2 = 2x^(6 - 2)
= 2x^4 (solution)

Ibai has taken 2/5 out of a barrel of beer, Ane has drawn a third. It expresses in graphic and numerical form: a) The fraction that they have drawn between the two. b) Which of them has gotten the most?
Answer:
7/15
Step-by-step explanation:
2/5 + 1/3 is the same as 2/5 + 5/15.. so we add them together to get 7/15. This can not be simplified further
To know who has gotten most I like to think in percentage terms. 2/5 is the same as 40% (2/5 is the same as 4/10 = 40/100 =40%). 1/3 is 33.33% so Ane got more
Answer:
A. 11/15 B. Ibai.
Step-by-step explanation:
First, find the Least Common Multiple, or LCM, of the denominators, which is 15. Then, multiply each denominator by the number that gets the denominator to 15, which is the LCM. Next, multiply the numerator by the same number you multiplied the denominators, which was 3 for Ibai, and 5 for Ane. Finally, compare the two numbers to see which is higher. In this case, Ibai took out 6/15, while Ane took out 5/15, meaning Ibai took out more than Ane. Also, together, Ibai and Ane both drew out 11/15 together.
Sebastian scored a 94% on a test. Frankie answered 43 questions correctly out of 50 total questions. Who scored higher on the test?
Answer:
Sebastian did.
Step-by-step explanation:
seb = 94% or 47/50
while frankie = 43/50 or 86%
Also look at 50 if you want and you can see it divides evenly with 100. Basically each mistake you make is 2 percent lost.
Answer: Sebastian
Step-by-step explanation: Divide 43 by 50.
43/50=0.86
tests are graded by the decimal point so he got 86%
since 94% is more than 86% sebastian scored higher
Kalinda is 68.7 inches tall and wants to know how many inches taller she is than Terrence. If t represents Terrence's height in inches, which expression can she use to find the answer? 68.7 minus t StartFraction t Over 68.7 EndFraction StartFraction 68.7 Over t EndFraction t minus 68.7
Answer:
68.7 - t
Step-by-step explanation:
Here, we are interested in giving the expression that Kalinda can use to know the difference in height between her and Terrence
From the question, Kalinda is 68.7 inches tall while Terrence is t inches tall
To know the difference in their heights, we simply subtract Terrence’s height from Kalinda’a
Mathematically, that would be 68.7 - t
Answer:
Its A

3x+2(5x-3)=7
with steps
Answer: x=1
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*x+2*(5*x-3)-(7)=0
3x + 2 • (5x - 3)) - 7 = 0
Pull out like factors :
13x - 13 = 13 • (x - 1)
13 = 0
A a non-zero constant never equals zero.
Solve : x-1 = 0
Add 1 to both sides of the equation :
x = 1

Use the figure to find measures of the numbered angles.
Answer:
1 = 137
2 = 43
3 = 43
4 = 137
Step-by-step explanation:
for the first line, do (180-137 = 43)
then, 43 would be corresponding angle to 2 - making them equal
2 would be vertically opposite to 3, making them equal
137 and 1 are corresponding- making them equal
4 is vertically opposite to 1 - making them equal

Which symbol correctly compares the fractions?
−5/6 −13/15
a. >
b. <
c. =
From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15
For us to compare negative fractions, we must know that higher negative fractions are less than the smaller ones
Given the fractions −5/6 and −13/15
First we will need to write this fractions as percentage:
-5/6 * 100 = -500/6 = -83.3%
-13/15 * 100 = -1300/15 = -86.67%
From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15

PLZ HELP I WILL MARK BRAILNLEIST!! 20. b) Find the side length of the square. [No label is required.] *
1 point
2x + 5 ft
6x – 11 ft
Your answer
This is a required question
Answer:
The length of one side is 13 feet.
Step-by-step explanation:
To start, a square is 4 sides that are equal in length. This means that when you have a problem like this, you need to set the equations equal to each other like:
[tex]2x+5=6x-11[/tex]
In order to solve a problem like this, with the same variables on different sides, start by subtracting the smaller variable from both sides. In this case, you would be subtracting 2x from both sides, which would leave us with:
[tex]5=4x-11[/tex]
After that, you solve it like a normal one-step equation. Add 11 to both sides.
[tex]16=4x[/tex]
Now, divide both sides by 4 and you will know how much [tex]x[/tex] is worth.
[tex]4=x[/tex]
Now that we know how much [tex]x[/tex] is worth, we can plug that into either of the equations given to us. It doesn't matter which since they are equal to each other.
[tex]2(4)+5[/tex]
That would give us 13.
Answer:
the sides are 13
x= 4
Step-by-step explanation:
2x+5 = 6x-11 subtract five from both sides
2x = 6x-16 subtract 6x from both sides
-4x = -16 divide both sides by -4
x = 4 substitute into original problem
2(4) + 5 = 6(4) - 11
8 + 5 = 24 - 11
13 = 13

Given:
Two triangles are congruent, i.e., [tex]\Delta ABC\cong \Delta XYZ[/tex].
To find:
All the measures of both triangle.
Solution:
We have,
[tex]\Delta ABC\cong \Delta XYZ[/tex].
We know that, corresponding parts of congruent triangles are congruent (CPCTC).
[tex]\angle A=\angle X[/tex]
[tex]\angle B=\angle Y=90^\circ[/tex]
[tex]\angle C=\angle Z=37^\circ[/tex]
It triangle ABC,
[tex]\angle A+\angle B+\angle C=180^\circ[/tex] (Angle sum property)
[tex]\angle A+90^\circ+37^\circ=180^\circ[/tex]
[tex]\angle A+127^\circ=180^\circ[/tex]
[tex]\angle A=180^\circ -127^\circ[/tex]
[tex]\angle A=53^\circ[/tex]
So,
[tex]\angle A=\angle C=53^\circ[/tex]
[tex]AB=XY=3\text{ units}[/tex]
[tex]BC=YZ=4\text{ units}[/tex]
[tex]AC=XZ=5\text{ units}[/tex]
Therefore, m∠A = 53˚, m∠B =90˚ , m∠C =37˚ , m∠X = 53˚, m∠Y =90˚ , m∠Z =37˚ , Segment AB = 3 units , Segment BC = 4 units , Segment AC = 5 units , Segment XY = 3 units , Segment YZ = 4 units , Segment XZ = 5 units .
