Brendan is going to paint a wall that measures 10 feet tall by 13 feet wide. The wall has two windows that are 2.5 feet wide by 4 feet tall. What is the area of the wall that he is going to pain

The area of the wall Brenda is going to paint = 110 sq. ft.

Recall:

Given:

Measurement of the wall = 10 feet tall by 13 feet wide

Area of the wall = 10 × 13 = 130 sq. ft

Measurement of a window = 2.5 feet wide by 4 feet tall

Area of a window = 2.5 × 4 = 10 sq. ft

The windows won't be painted, therefore, the area of the wall that Brenda is going to paint = Total area of the wall - 2(Area of a window)

Area of the wall to be painted = 130 - 2(10)

Total area of paint = 110 ft²

Step-by-step explanation:

Given:

Measurement of wall = 10 feet tall by 13 feet wide

Measurement window = 2.5 feet wide by 4 feet tall each

Find:

Total area of paint

Computation:

Total area of paint = Area of wall - 2[Area of window]

Total area of paint = [10 x 13] - 2[2.5 x 4]

Total area of paint = [130] - [20]

Total area of paint = 110 ft²

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
