Arectangle has a width of 3 cm and a length of 10 cm.

what is the effect on the perimeter when the dimensions are multiplied by 10?

a. the perimeter is increased by a factor of 10.

b. the perimeter is increased by a factor of 40.

c. the perimeter is increased by a factor of 100.

d. the perimeter is increased by a factor of 400.

A. The perimeter is increased by a factor of 10.

Step-by-step explanation:

The width of the rectangle = 3,

Length of the rectangle = 10,

Thus, the initial perimeter of the rectangle = 2(3+10) = 2(13) = 26

After the  dimensions are multiplied by 10,

The new width of the rectangle = 30,

Length of the rectangle = 100,

Thus, the new perimeter of the rectangle = 2(30+100) = 2(130)=260

⇒

⇒

Hence, the perimeter is increased by the scale factor 10.

⇒ Option A is correct.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
