Kylie is wrong about the result since <span>(–4x + 9)2 will result to a perfect square trinomal. Any binomial squared will always result to a perfect square trinomial.
</span>And the expansion of the expression should be
<span>(–4x + 9)2 = </span>(-4x)2 + 2(-4x)(9) + 9^2
(–4x + 9)2 = <span>16x2 - 72x + 18
She missed doing the middle term in doing the multiplication

Okay, So We Need To Find 15% Of 80.
Set Them Up As A Fraction Equation.
X 15
--- = ---
80 100
Multiply Means And Extremes.
100X = 80*15
Simplify.
80 * 15 = 1200
So;
100x = 1200
Now, Divide:
100x/100 = 1x = x
X = 1200/100
1200/ 100 = 12.
So:
X = 12.
This Means, 15% Of 80 Is 12.
Answer:
Yes, it is -6
Step-by-step explanation:
That is because the square root of 9 is 3 and the square root of 144 is 12, so after taking the square roots you have: 3*12 -42 = -6
Answer:
572.56
Step-by-step explanation:
V=π r2h
3=π·4.52·27
3≈572.55526
16, 24, 32
and it goes on, and on.
