The perimeter of a shape is the sum of its side lengths
The expressions for the perimeter of the frame are 4(l + 2) and 4l + 8
<h3>How to determine the perimeter of the shape</h3>The side length of the frame is given as l
So, the perimeter of the frame is
:
When 2 inches are added to each length, the perimeter of the frame becomes
Expand
Hence, the expressions for the perimeter of the frame are 4(l + 2) and 4l + 8

Answer: x = -7
Concept:
From the given graph, we can see that it is an isosceles triangle since the two base angles are congruent.
In geometry, an isosceles triangle is a triangle that has two sides of equal length.
If you are still confused, you may refer to the attachment below for a graphical explanation or tell me.
Solve:
<u>Given information</u>
First Side = 7
Second Side = x + 14
<u>Given expression deducted from the definition of an isosceles triangle</u>
Second Side = First Side
<u>Substitute values into the expression</u>
x + 14 = 7
<u>Subtract 14 on both sides</u>
x + 14 - 14 = 7 - 14
