When we are multiplying terms with exponents and the bases are the same, we can add the exponents
A^m * A^n =
A ^ ( m+n)
Answer:
m and n
Step-by-step explanation:
Exponents are the raised numbers or letters.
So it is m and n

What is the prime factorization of 90?
====================================================
Explanation:
Divide by the smallest prime 2
90/2 = 45
Then divide by the next smallest prime 3 (since 2 won't go into 45)
45/3 = 15
Repeat the last step
15/3 = 5
We stop because the result is prime.
Note the denominators are 2, 3, 3. The final result is 5 which is prime.
So the prime factors are 2, 3, 3, and 5
They multiply to 2*3*3*5 = 90.
We can condense it to 2*3^2*5 = 90 because 3*3 = 3^2.
Answer and Step-by-step explanation:
The prime factorization of 90 is 2 × 3 × 3 × 5 or 2 × 32 × 5, where 2, 3, and 5 are the prime numbers. You can find "prime factorization" by following two simple steps. Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Step 2: Write the number as a product of prime numbers.

Solve for k.
6 + -4k = 18
k=
k=-3
6*(-4k)=18
subtract 6 from both sides
-4k=12
divide by -4 on both sides
k=-3
Answer:
[tex] \sf \: k = - 3[/tex]
Step-by-step explanation:
Now we have to,
→ Find the required value of k.
The equation is,
→ 6 + (-4k) = 18
Then the value of k will be,
→ 6 + (-4k) = 18
→ 6 - 4k = 18
→ -4k = 18 - 6
→ -4k = 12
→ k = 12 ÷ (-4)
→ [ k = -3 ]
Hence, the value of k is -3.

-2(x+1)(x-2) what is the y-intercept?
Answer:
The y-intercept is at 4.
Step-by-step explanation:
When trying to find the y-intercept, you want to substitute your x's with 0 as x must equal 0 for your y-intercept. This gives you -2(0+1)(0-2). From here, you want to simplify your parenthesis equations.-2(1)(-2) Then you want to solve which gives you 4.

Answer:
Each side is 4 cm.
Step-by-step explanation:
We need to try to express the perimeter of the figure in terms of "square sides". Basically, we're going to count how many square sides the perimeter is.
Starting from the top, the very top is 1 side.
Moving down to the right, we have another side.
Then half a side as we go to the right edge.
The right edge is 1 full side.
Another half side, going left.
Going down, we have 1 full side.
The other side is mirrored, meaning we just have to double this to get the full figure's perimiter.
Counting up our sides (we'll call one side [tex]s[/tex] ), we have:
1s + 1s + 0.5s + 1s + 0.5s + 1s = 4s + 0.5s + 0.5s = 5s
Doubling it:
5s * 2 = 10s
The whole perimiter is 8 square sides. Since we know the perimeter is 40 cm, we can find the length of one side by solving this equation:
10s = 40
Dividing both sides by 10:
s = 40/10 = 4
Answer: Each side is 4 cm.
A shirt is on sale for 40% off. The sale price is $12. How much was the original price? *
Answer:
$20
Step-by-step explanation:
Let the variable x in this equation represents the original price of the shirt:
100% - 40% = 60%
60% of x = $12
0.6x = $12
x = $12/0.6
x = $20
A plane traveled 360 miles each way to Athens and back. The trip there was with the wind. It took 3 hours. The trip back was into the wind. The trip back took 6 hours. Find the speed of the plane in still air and the speed of the wind.
Answer:
S=32.5
W=97.5
Step-by-step explanation:
S=speed of plane in still air
W=speed of wind
-----------------------------------------
3(S+W)=130
6(S-W)=130

S+W=43.33333...
S-W=21.66666...
2S=64.999...
S=32.5(simplified)

Pythagorean theorem
Answer:
8.7
Step-by-step explanation:
hypotenuse= 14 =c
a=11
b=x
a²+b²=c²
b²=c²-a²
b²=14²-11²
b²= 196-121
b²=75
b=√75=5√3=8.7 rounded to the nearest tenth
Final Answer:
x = 8.66
Step-by-step explanation:
formula: [tex]b=\sqrt{c^2-a^2}[/tex]
a = 11
b = x
c = 14
[tex]b=\sqrt{14^2-11^2}[/tex]
[tex]b=\sqrt{196-121}[/tex]
[tex]b=\sqrt{75}[/tex]
b = 8.66025
x = 8.66
rounded off to the nearest hundredths: 8.66

Plot two points to form a square in the above graph.Label the points R and S. A square is a quadrilateral with all four sides of the same length. After plotting the points, trace the square by connecting the points.
PART B
To find the perimeter of a polygon, take the sum of the length of each side. What is the perimeter of the square that you created in part A? Round your answer to two decimal places.
Answer:
Perimeter = 28.84 m
Step-by-step explanation:
Since the other two points will make the shape to look like a square, each length of the square will be equal.
We can therefore find the length PQ by using the formula
L = sqrt ( [ X2 - X1 ]^2 + [ Y2 - Y1 ]^2
L = sqrt( [ -2 + 4 ]^2 + [ 4 + 3]^2
L = sqrt (4 + 49)
L = sqrt (52)
L = 7.2 m
Each length of the square is 7.2 m approximately
The parimeters will be:
Perimeter = 4L
Perimeter = 4 × 7.2
Perimeter = 28.84 metres
Therefore, the perimeter of the square is 28.84

In the diagram, line segment CD is the perpendicular bisector of line segment AB, and E is a point not on either line that is on the same side of segment CD as point A.
Is point E closer to point A, closer to point B, or the same distance from both points? Explain how you know.
Answer:
E would be closer to A
explanation:
if they were the same distance from both A and E it would be a point on the line CD, and if it was closer to E it would be on the other side of line CD.

Please please help ASAP! Classify each angle!
Answer:
Acute Angles: ∠TLS, ∠SLT, ∠ULR Right Angles: --------- Obtuse Angles: ∠RLT, ∠SLU, ∠ULS, Straight Angles: ∠RLS, ∠TLU Not angles: ∠TRLStep-by-step explanation:
The lines intersect at point L, so all angles have a vertex (middle letter) L so there is no angle TRL
Straight angle is a line with dot-vertex, so the straight angles are ∠RLS and ∠TLU.
∠TLS is less than 90° then it is acute angle (∠SLT is the same angle). ∠ULR is vertex angle to ∠TLS, so it's also acute angle.
Two angles adding to straight angle mean that they are both right angles or one is acute and the second is obtuse. ∠TLS is acute so ∠RLT is obtuse (they adding to ∠RLS) and ∠SLU is obtuse (they adding to ∠TLU). ∠ULS is the same angle as ∠SLU.

a. The same line
(Choice B)
Distinct parallel lines
(Choice C)
Perpendicular lines
(Choice D)
Intersecting, but not perpendicular lines
Answer:
C
Step-by-step explanation:
Both the given equations are of Perpendicular lines.
What are Perpendicular lines?Perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).
Given are two equations of lines
y-2= x+20
y = x+20+2
y = x+22.....(i)
y-2= -(x+20)
y = -x-20+2
y = -x-18,,,,,,,(ii)
The slopes of the equation are 1 and -1, We know that perpendicular lines have slopes that are negative reciprocals of one another.
Hence, The lines given are perpendicular lines
