Answer:

Tamara needs to cover a total of 476 square feet.
Tamara will have enough material to cover all four walls.

Step-by-step explanation:

If the room dimensions are 8 1/3 feet by 11 1/2 feet, the perimeter length is ...

P = 2(L+W) = 2(8 1/3 +11 1/2) = 2(19 5/6) = 39 2/3 feet

The area of the walls is the product of this perimeter length and the height of the wall. If that height is 12 feet, then the wall area is ...

A = PH = (39 2/3 ft)(12 ft) = 476 ft²

Tamara needs to cover a total of 476 square feet.

If Tamara orders 480 square feet of material, ...

Tamara will have enough to cover all four walls.

Given:

In parallelogram ABCD, two of its vertices are A(-4,0) and B(0,3).

To find:

The equation that represents a line that contain CD.

Solution:

We have,

A(-4,0) and B(0,3)

Slope of AB is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{3-0}{0-(-4)}$

$m=\dfrac{3}{4}$

The slope of line AB is $\dfrac{3}{4}$ .

Opposite sides of a parallelogram are parallel and slopes of parallel lines are equal.

In parallelogram ABCD, AB and CD are opposite sides. So, their slopes must be equal.

Slope of line AB = Slope of line CD = $\dfrac{3}{4}$

The slope intercept form of a line is

$y=mx+b$

Where, m is slope and b is y-intercept.

Slope of line CD is $\dfrac{3}{4}$ , it means the line must be of the form

$y=\dfrac{3}{4}x+b$

Coefficient of x is $\dfrac{3}{4}$ only in option a.

Therefore, the correct option is a.
