I’m pretty sure the answer is -237, -236, -235, and -234. Because -234 would be the greatest of that consecutive set.
First let's rewrite it...
18a^2 + 20a + 8
Factor out a 2
2 (9a^2 + 10a + 4)
<span>inversely
y = k/x
k = yx
k = 10*10 = 100
when y = 20
20 = 100/x
20x = 100
x = 5
answer
</span><span> x = 5 when y is 20</span>
The commutative property of multiplication is ab=ba
so
9(x+5)=(x+5)9
(note, some people on this site like to write x2 for x² but that's not how you math correctly., (x+5)9 doesn't mean (x+5)⁹, it means (x+5) times 9)
