Answer:
(1,2)
Step-by-step explanation:
i am right good lucky
From the text you can derive the following equations:
(1) A = bh/2 = 8
(2) and h = b+6
Fill in h in (1):
b(b+6)/2 = 8 => b^2 + 6b = 16 with the quadratic formula or simply trying some values for b you can find b=2, so h=8.
Answer: 30
Step-by-step explanation:
rs + 2s when r = 8 and s = 3
8(3) + 2(3)
8 * 3 = 24
2 * 3 = 6
24 + 6 = 30
