Answer:
-60
Step-by-step explanation:
Factor the problem out using FOIL.
The end result is: −60
−84x+9
The value of coefficent a (the number in front of the x^2) is -60.
Formula for Perimeter of Rectangle:
P = 2(L + W)
Plug in 160:
160 = 2(L + W)
L = 4W
So we can plug in '4W' for 'L' in the first equation.
<span>160 = 2(L + W)
160 = 2(4W + W)
Combine like terms:
160 = 2(5W)
160 = 10W
Divide 10 to both sides:
W = 16
Now we can plug this back into any of the two equations to find the length.
L = 4W
L = 4(16)
L = 64
So the width is 16, and the length is 64.</span>
Answer:
The answer stays the same.
Step-by-step explanation:
For example, if you have 1/2 and multiply the numerator and the denominator by 4, you get 4/8. 4 divided by 8 still gives you 1/2.
