Answer:
4 ft
Step-by-step explanation:

A=10 h=5

20=5b (multiply both sides by 2)

Answer:
9
Step-by-step explanation:
KL + KJ = 17
2 + 3x + 5x - 1 = 17 add like terms
8x + 1 = 17 subtract 1 from both sides
8x = 16 divide both sides by 8
x = 2
KL = 5x - 1 replace x with 2
5*2 - 1 = 9
-2x cube + 2x cube makes 0, so u can delete it,
then 6x + 10x makes 16x,
so the final answer should be 16x+7xtothepower4
