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;
-2x-7=3
or,-2x=10
or,x=-5
Since we`ve got the value of x.let`s substitute it in 9x-7
=9×(-5)-7
=-52
