The parallelogram shown below has an area of 24 units2.
Ber [7]

Answer:

9

===================================================

Explanation:

The area of the parallelogram is equal to the base times height. The formula to use is A = b*h. The height and base are always perpendicular to one another.

The base is some unknown variable b. Multiply the base by the height 15 to get 15*b which is equal to the area 135

Therefore, 15*b = 135

Divide both sides by 15 and we isolate b

15b = 135

15b/15 = 135/15

b = 9

So the base is 9

Check:

area = base*height = 9*15 = 135

so the answer is confirmed

side note: we never use the value 17 at all. It is likely put in there as a distraction.

Explain how to find the value of z if you know that 100x*2 + 120x + z is a perfect square trinomial
wariber [46]
Divide the value of "b" by 2 and then square it.

   (b / 2)²
= (120 / 2)²
= (60)²
= 3600

Therefore the value of z is 3600. That's at least what I believe lol
