A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7. 1. What are the side lengths of the scaled copy?

2. Suppose you want to scale the copy back to its original size. What scale factor should
you use?

Step-by-step explanation:

Given

Rectangle:

Length = 2 in

Width = 3 in

Scale Factor = 7

Solving (a):

The side lengths of the new scale is calculated as follows;

New Lengths = Old Lengths * Scale Factor

Solving (b): To go back to the original length

Given that the initial scale factor is 7;

The new scale factor is the reciprocal of the old factor;

Hence;

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
