Find the Dimensions of Rectangle ABCD
Perimeter of ABCD= 80
(Pythagorean Theorem)
Will mark brainliest!
Answer:
xy + 2x + 2y = (42)(80)
x2 + 80x - 42 = 0
x2 - 42x + 80 = 0
x2 - 21x + 80 = 0
Step-by-step explanation:
The dimensions of the rectangle ABCD is 24 x 16
What is the Perimeter of a Rectangle?The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P of rectangle = 2 ( Length + Width )
Given data ,
Let the dimensions of the rectangle be represented as L x W
where L and W are the length and width of the rectangle
The perimeter of the rectangle P = 80
Now , measure of side E F of triangle is given by the Pythagoras Theorem
And , E F = √ ( A F )² - ( E A )²
On simplifying the equation , we get
The measure of side E F = √ ( 625 - 400 )
The measure of side E F = √225 = 15
Now ,
The measure of side EC of triangle is given by the Pythagoras Theorem
And , EC = √ ( E F )² - ( C F )²
On simplifying the equation , we get
The measure of side E C = √ ( 15 )² - ( 9 )²
The measure of side E C = √ ( 225 - 91 )
The measure of side E C = √144
The measure of side E C = 12
So , the length of the rectangle B C = E B + B C = 12 + 12
The length of the rectangle B C = 24
The width of the rectangle is A B = W
Perimeter P of rectangle = 2 ( Length + Width )
Substituting the values in the equation , we get
80 = 2 ( 24 + W )
Divide by 2 on both sides of the equation , we get
24 + W = 40
Subtracting 24 on both sides of the equation , we get
W = 16
Hence , the dimensions of the rectangle is 24 x 16

Answer:
B. 35 dollars
Step-by-step explanation:
So first you have to subtract 20 from 160 because that is the only cost that we definitely know. 160-20=140
Then you have to divide 4 from 140 because the sweaters cost the same amount and she bought 4 of them and 140 divided by 4 is 35
So each sweater coat 35 dollars

you should know: in all means in total, so simply you add everything up.
answer:
1 + 2/4 + 3/4
- convert 1 to a fraction so its easier to add.
1 = 4/4 (must have the same denominator to add)
4/4 + 2/4 + 3/4
- add the numerators (top), NOT the denominators (bottom)
you get: 9/4 (this is an improper fraction, so you convert this into a mixed number)
9/4 = 2 1/4
FINAL ANSWER: (its a mixed number)
2 1/4

The answer is [tex]d(t)=3,906,000[/tex] miles.
Step-by-step explanation:
To solve this is pretty easy,
We know that the equation is [tex]d(t)=186000t[/tex], and since we have to find the distance in 21 seconds, you just have to substitute the variable.
[tex]t=time\\d(t)=186000(t)\\d(21)=186000(21)\\d(21)=3,906,000[/tex]

6x - y =4 and y = 4x + 2. Solve the system and find x - 2y
Answer:
x = 3
x - 2y = -25
Step-by-step explanation:
Since y = 4x + 2 put (4x + 2) into the first equation in place of y:
6x - (4x + 2) = 4
To get rid of the parenthesis change 4x to -4x and 2 to -2:
6x - 4x - 2 = 4
If you combine the x’s you will now have only 2x
2x - 2 = 4
To get x by itself we add 2 to both sides
2x = 6
Divide by 2 on both sides:
x = 3
_______________________________
For the last equation (x - 2y) we put (4x + 2) in place of y again:
x - 2[4x + 2]
We know the value of x already:
3 - 2[4(3) + 2]
Now solve for the things in parenthesis:
3 - 2(14)
3 - 28
Subtract to get the answer:
-25

[tex]Point Form:(1,2)\\Equation Form:x=1,y=2[/tex]
Step-by-step explanation:
Let's solve your system by substitution.
[tex]6x-y=4;y=4x+2x-2y[/tex]
Step: Solve 6x−y=4for y:
[tex]6x-y=46x-y+-6x=4+-6x[/tex]
[tex]-y=-6x+4[/tex]
[tex]\frac{-y}{-1} =\frac{-6x+4}{-1}[/tex]
[tex]y=6x-4[/tex]
Step: Substitute 6x−4 for y in y=6x−2y:
[tex]y=6x-2y\\6x-4=6x-2(6x-4)[/tex]
[tex]6x-4=-6x+8[/tex]
[tex]6x-4+6x=-6x+8+6x\\12x-4=8\\12x-4+4=8+4[/tex]
[tex]12x=12\\\frac{12x}{12} =\frac{12}{12}[/tex]
Step: Substitute 1 for x in y=6x−4:
[tex]y=6-4\\y=(6)(1)-4\\y=2[/tex]
Answer:
[tex]x=1 , y=2[/tex]

Answer:
-512
Step-by-step explanation:
The laws of exponents state that multiplying two exponents together of the same base allows you to add the exponents. Raising an exponent to another power allows you to multiply the exponents. In this case. you have [tex](-2)^3*((-2^3))^2[/tex]. First, you take the second term, or [tex]((-2^3))^2[/tex] and simplify it. Since you're raising an exponent to another exponent you have [tex](-2)^(3*2)[/tex], or [tex](-2)^6[/tex]. Now, you multiply by [tex](-2)^3[/tex]. Since they both have the same base, you can add the exponents to get [tex](-2)^9[/tex]. Since [tex](-2)^9[/tex] is raised to an odd exponent, you know you're answer is going to be negative. [tex]2^9[/tex] is 512, so that negative would be -512. If you're looking for an expression for this, you can write [tex](-2)^9[/tex]

8/3+2/3= 10/3 = 3 1/3
10/3+2/3=12/3 = 4
12/3+2/3=14/3 = 4 2/3
14/3+2/3=16/3 = 5 1/3
16/3+2/3=18/3 = 6
18/3+2/3=20/3 = 6 2/3
20/3+2/3=22/3 = 7 1/3
22/3+2/3=24/3 = 8
24/3+2/3=26/3 = 8 2/3
26/3+2/3=28/3 = 9 1/3
28/3+2/3=30/3 = 10
30/3+2/3=32/3 = 10 2/3
32/3+2/3=34/3 = 11 1/3
34/3+2/3=36/3 = 12
