Answer:
d. p = 2*20 + 2*10
Step-by-step explanation:
You know to find the perimeter, just add side + side + side + side.
And two pairs of sides on a rectangle are congruent, so the missing side lengths based on the width and length, will be 20 & 10.
So add 20 + 20 + 10 + 10.
To simplify this, say 2*20 and 2*10. And then add them.
So it is D
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
Doing the multiplication we have:

From here, we clear the value of x.
We have then:

Therefore, we have:
Answer:
7 times 1/7 equals 1
Using the pairs (1,32) and (2,64) the rate of speed is (64-32 / 2-1 = 32 feet per second.
To find the rate of decent you would multiply the rate by time:
The equation is y = 32x
B. Replace x with 15 and solve for y:
Y = 32(15)
Y = 480
The rate of speed is 480 feet per second.
