Hey there! :)

Answer:

r = 20.

Step-by-step explanation:

Given:

-4 = r/20 - 5

Begin by adding 5 to both sides:

-4 + 5 = r/20 - 5 + 5

1 = r/20

Multiply both sides by 20:

1 · 20 = r/20 · 20

r = 20.

rosijanka [135]
Slope is\text{m}=\frac{y_1-y_2}{x_1-x_2}=\cfrac{10-2}{1-(-3)}
Then you use the equation
\text{y=mx+b}
Where b is the y-intercept. To find it, plug in x and y from one of the points. Say, point 1 (1,10):
10=m(1)+b
You know m (from above) and now you can solve for b.

Rearrange terms:
y-b=mx

And that will be the answer.

Make sense?

scoray [572]
<span>length = 7x
</span><span>width = 2x

2(7x + 2x) = 72
7x + 2x = 72/2
9x = 36
x = 36/9
x = 4
</span>
width = 2x = 2 * 4 = 8 units<span>
