Answer:

<h2>42 {m}^{3}  + 64 {m}^{2}  + 52m + 24</h2>

Step-by-step explanation:

(7m + 6)(6 {m}^{2}  + 4m + 4)

= 7m(6 {m}^{2}  + 4m + 4) + 6(6 {m}^{2}  + 4m + 4)

= 42 {m}^{3}  + 28 {m}^{2}  + 28m + 36 {m}^{2}  + 24m + 24

= 42 {m}^{3}  + 64 {m}^{2}  + 52m + 24( ans)

What is the slope ( 6, 5 ) and ( -6,9 )
Ronch [10]

Answer:

\large\boxed{slope=-\dfrac{1}{3}}

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

(x₁, y₁), (x₂, y₂) - points on a line

We have the points

(6, 5) → x₁ = 6, y₁ = 5

(-6, 9) → x₂ = -6, y₂ = 9

Substitute:

m=\dfrac{9-5}{-6-6}=\dfrac{4}{-12}=-\dfrac{4:4}{12:4}=-\dfrac{1}{3}
