A. Write an expression for the area of the shaded region. b. Write the expression in factored form.

A.

B.

Step-by-step explanation:

A. The area of the shaded region = area of the whole large square - area of the 4 smaller squares

= (5x*5x) - 4(4*4)

Area of shaded region =

B. The expression, , is the difference of two perfect squares, 25x² and 64. Therefore, apply the rule of factoring difference of two perfect squares.

Thus,

Therefore, the expression of the are of the shaded region can be expressed in factored form as:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
