Question

PLEASE HELP ASAP!!!!! please help me!!

Answer 1

Answer:

Step-by-step explanation:

A)

The parallelogram area formula is  b*h  just like a square but the height is the distance from the base to the parallel top .. not the side length.. that's the only difference.

the base is  x+4

total area is 5x+20

so use those in our formula

area = b*h

5x+20 = x+4 * h   now solve for h   (yes we'll have an x in the other side, but that's okay b/c their formulas do also)

(5x + 20) / (x+4) = h

B)

area = b*h

8x-24 = b*8

(8x-24)/8 = b

8x/8  - 24/8  = b

x -3 = b

C)

area = b * h

12x + 6y = 6 * h

(12x + 6y) / 6 = h

12x/6  + 6y/6  = h

2x + y = h

voila you're don :)
