Answer:

<h2>(7 - 4n) · 6 = 42 - 24n</h2>

Step-by-step explanation:

The distributive property: <em>a(b - c) = ab - ac</em>

(7 - 4n) · 6 = (7)(6) - (4n)(6) = 42 - 24n

Whats the slope and the equation
vichka [17]
You can find the slope of a line by having two points. In this case we have 5 different point so we pick two.

so for the first one I will pick (2,17) and (7,37)

we use (y2-y1) / (x2-x1)  this is rise over run

plug and chug to get slope.
(37-17)/(7-2)= 4 

now use point slope using one of the point that we used to find the slope
y−b=m(x−a<span>) or y-y1 = m (x-x1)

plug and chug again
m=4 ............ point (2,17)

y- 17 = 4 (x- 2)
y= 4x +10 

hope this helps

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.
