Answer:

(6m-7)\cdot4 is equivalent to 24m-28

Step-by-step explanation:

The distributive property enables us get rid of parentheses by multiplying the term outside by each of the term inside; a bit like algebraic expansion

It states that:

(a+b)\cdot c = a\cdot c+ b\cdot c

Therefore (6m-7)\cdot4=6m\cdot4-7\cdot4=24m-28

Thus 24m-28 is the equivalent expression

Two similar cylinders have radii of 15 inches and 6 inches. What is the ratio of the surface area of the small cylinder to the s
Levart [38]

Answer:

4:25

Step-by-step explanation:

Given that,

r₁ = 15 inches, r₂ = 6 inches

The area of the cylinder is given by :

A=2\pi rh+2\pi r^2

The ratio of surface areas of two cylinders,

\dfrac{S_2}{S_1}=\dfrac{2\pi r_2h_2+2\pi r_2^2}{2\pi r_1h_1+2\pi r_1^2}\\\\\dfrac{S_2}{S_1}=(\dfrac{r_2}{r_1})^2\\\\=\dfrac{6}{15}^2\\\\=\dfrac{4}{25}

Hence, the required ratio is 4:25.

2x - 7 = -X-1<br> What is that answer to this
denis23 [38]

Answer:

x = 2

Step-by-step explanation:

2x - 7 = -x - 1

(add x on both sides)

3x - 7 = -1

(add 7 on both sides)

3x = 6

(divide both sides by 3)

x = 2
