Question 7: Choose the correct simplification of the expression (3x − 6)(2x2 − 4x − 5)

Answer:

7. 6x³ - 12x² + 12x + 15

Step-by-step explanation:

(3x-6)(2x² - 4x - 5)

3x • 2x² = 6x³

3x • -4x = -12x²

3x • -5 = -15

-6 • 2x² = -12x²

-6 • -4x = 24x

-6 • -5 = 30

combine terms

6x³ - 12x² - 15 - 12x² + 24x + 30

combine like terms

6x³ - 24x² + 24x + 15

hope this helps :)

in the future, only ask one question per brainly submission. thanks!

A triangle has legs that are 7in and 24in long. How long is the hypothenuse?
SashulF [63]

Answer: 25 in

Step-by-step explanation:

<u>Due to the use of the term "hypotenuse" I will assume the triangle is a right triangle.</u>

<u></u>

According to pythagorean theorem, 7²+24²=(hypotenuse)²

49+24²= (hypotenuse)²

49+576= (hypotenuse)²

625 = (hypotenuse)²

25 = hypotenuse

Hope it helps <3 :D
