Help Me I am really confused on how to solve this math problem
rjkz [21]

Answer:

e(x) = d(x)+4

Step-by-step explanation:

d(x) = ( x +2)^2 -4

Add 4 to each side

d(x) +4 =  ( x +2)^2 -4+4

d(x) +4 =  ( x +2)^2

We know that (x=2)^2 = e(x)

d(x) +4 =  e(x)

e(x) = d(x)+4

Identify the area of the trapezoid.
Vlad1618 [11]

Option B: The area of the trapezoid is 157.5 m²

Explanation:

We need to determine the area of the trapezoid.

The area of the trapezoid can be determined by the formula,

Area=\frac{h}{2} (a+b)

where h is the height, a and b are the base of the trapezoid.

From the figure, it is obvious that a=14 , b=7 and h=15

Substituting these values in the formula, we have,

Area=\frac{15}{2} (14+7)

Simplifying the terms, we have,

Area=\frac{15}{2} (21)

Multiplying the terms in the numerator, we have,

Area=\frac{315}{2}

Dividing, we get,

Area= 157.5 \ m^2

Thus, the area of the trapezoid is 157.5 m²

Hence, Option B is the correct answer.
