Answer:
B
Step-by-step explanation:
Given
(4x² - 3x - 4) - (3x² + 4x - 8) ← distribute by - 1
= 4x² - 3x - 4 - 3x² - 4x + 8 ← collect like terms
= x² - 7x + 4 → B
Answer:
16 ft
Step-by-step explanation:
Hi there,
The formula for the area of a rectangle is A = b*h.
So, let's start out by plugging in what we know.
240 = 15h
Now, solve for h by dividing both sides by 15
h = 16
So, the height of the rectangle is 16 ft
Hope this helps! Stay safe!

(-8)/(2y-8)=(5/(y+4))-7y+(8/(y^2-16))
(-4)/(y-4)=(5/(y+4))-7y+(8/(y+4)(y-4))
((-4)(y+4))/((y+4)(y-4))=((5(y-4))/(y+4)(y-4))-(7y(y+4)(y-4))/(y+4)(y-4))+(8/(y+4)(y-4))
(-4(y+4))=(5(y-4))-(7y(y+4)(y-4))+8
-4y-16=5y-20-(7y(y^2-16))+8
-4y-16=5y-20-7y^3+112y+8
-4y-16=117y-7y^3-12
-4=(121-7y^2)(y)
None of these choices would be equal to -4
