Answer:
x = 24
Step-by-step explanation:
To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.

To solve for x, cross multiply:
44.8(35) = (x+4)(56)
1568 = 56x + 224
1344 = 56x
24 = x

The width of the mat around the photo is 3 inches
The combined area of the of the photo and math = 224 square inches
The combined area is represented as:
(2w +8)(2w + 10) = 224
Expand the equation using the distributive rule

Divide through by 4

Factorize the resulting quadratic equation to solve for w

w - 3 = 0
w = 3
w + 12 = 0
w = -12
