Answer:

The answer is 5(3x + 8)

Step-by-step explanation:

Find the Greatest Common Factor (GCF).

$gcf = 5$

Factor out the GCF.

$5( \frac{15x}{5} + \frac{40}{5} )$

Simplify each term in parentheses.

$5(3x + 8)$

hence, the answer will be 5(3x + 8).

Answer:

6 times larger

Step-by-step explanation:

First, find the area of both.

Mary: 4*5.5=22

Lisa: 24*5.5=132

Then find what multiplied by 22 would equal 132. This is easy because it's a multiple-choice question.

22*20=440, so A is incorrect

We already know they are not equal, so then B can be crossed out

22*3=66, C would be incorrect

Leaving the only choice left to be the correct answer

22*6=132

Answer:

$\huge\boxed{c)\ 15,\ 36,\ 39}$

Step-by-step explanation:

$\text{Let}\ a\leq b\leq c\ \text{the sides of the triangle}.\\\\\text{If}\ a^2+b^2=c^2\ \text{then a triangle is a right triangle}\\\\\text{If}\ a^2+b^2c^2\ \text{then a triangle is a acute triangle}$

$a)\ 28,\ 45,\ 53\\\\28^2+45^2=784+2025=3593\\53^2=2809\\\\28^2+45^2>53^2\to\text{acute triangle}\\\\b)\ 17,\ 22,\ 29\\\\17^2+22^2=289+484=773\\29^2=841\\\\17^2+22^2$
