Answer:

27 days

Step-by-step explanation:

Well, there's two ways we could do this (which I do). One way is easier with a calculator, one is useful when you cannot use a calculator.

<u>EASY CALCULATOR METHOD</u>

30% as a decimal is 0.3, so if you multiply 90 by 0.3, you can easily find 30%. So:

<em>90 x 0.3 = 27 days.</em>

<u>NON CALCULATOR METHOD</u>

To find 10% of something, we divide the original value by 10. Therefore, we just need to find 10% and multiply that value by 3 to get 30%. So:

<em>90/10 = 9 days (10%)</em>

<em>9 x 3 = 27 days (30%)</em>

<em />

Either way both give you the same answer of 27 days.

What is the answer to this question? Please
AnnZ [28]

Answer:

y² + 8y + 16

Step-by-step explanation:

Given

(y + 4)²

= (y + 4)(y + 4)

Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is

y(y + 4) + 4(y + 4) ← distribute both parenthesis

= y² + 4y + 4y + 16 ← collect like terms

= y² + 8y + 16

Factor: 2x + 2y<br> Show work please
bearhunter [10]

Answer:

2(x + y)

Step-by-step explanation:

You can pull out a 2 from the expression.

So divide 2x by 2 and 2y by 2.

2x/2 = x

2y/2 = y

2(x + y)
