Given:
The expression is

To find:
The expression which is not a correct way to rewrite the given expression.
Solution:
We have,

Using distributive property, we get


Using distributive property the given expression can rewritten as:

Only the expression in option A is not a correct way to rewrite the given expression because
is not distributed to
properly.
Therefore, the correct option is A.
Answer:
59 square inches.
Step-by-step explanation:
Equation for area of whole, large triangle:
A = 1/2(b)(h)
A = 1/2(13)(14)
A = 91 square inches
Equation for area of tiny, white triangle:
A = 1/2(b)(h)
A = 1/2(8)(8)
A = 32 square inches
Equation to find the area of the shaded region:
A = 91 - 32
A = 59 square inches
