Answer: length is 8
Step-by-step explanation:
its just 24 divided by 3 = 8
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!
ex: 5/25=1/5
5 divided by 5 is and 25 divided by 5 is 5.
1.Write down the factors for the numerator(top number) and the denominator(the number down below).
2.Find the largest factor that is common between the two.
3.Divide the numerator and denominator by the greatest common factor.
4.Write down the reduced fraction.
Hope this helps
Answer:
x = 8.75, y = 8.125
Step-by-step explanation:
The triangles are similar thus the ratios of corresponding sides are equal, that is
= ( cross- multiply )
8x = 70 ( divide both sides by 8 )
x = 8.75
And
= ( cross- multiply )
8y = 65 ( divide both sides by 8 )
y = 8.125
Answer:
-6
Step-by-step explanation:
Substitutet -7 for y in -3(9+y): -3(9 - 7) = -3(2) = -6
