2y^2+ 2(9y^2 -8)
= 2y^2+ 18y^2 -16 (distributive property)
= 20y^2 -16
The final answer is 20y^2 -16~
If you repost with a question or snapshot, I would be capable of answering it.
2+5+8+11+14+17+20+23+26+29+32+35
The second one is a perfect square trinomial
X^2+16x+64
A = L * W
(9/10) = (3/2) * W
Divide both sides (3/2)
(9/10) / (3/2) = W
(9/10) * (2/3) = W
18/30 = W
6/10 = W
W = 3/5 mile
