I think it would be x+y=3
Hope this helps
It’s 104 bcuase your just do that it says
Answer:
10.5 inches
Step-by-step explanation:
250% = 250/100 = 2.5
The plant grew 2.5 times its height in 5 weeks.
Be careful with the way you interpret "The plant grew by 250% of its height after 5 weeks." It means that in 5 weeks, the plant grew an amount equal to 2.5 times the original length of the plant. It does not mean that the total height at the end of 5 weeks was 2.5 times the original height.
growth is 5 weeks: 250% of 3 inches = 2.5 × 3 inches = 7.5 inches
height after 5 weeks: 3 inches + 7.5 inches = 10.5 inches
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
