HELP ME PLZZ I NEED HELP WITH THIS 50 POINTS!! Mr. Hamilton decorates his U. S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 3/4 feet long.

Each president's picture is 6 inches wide.

(THE FIRST PICTURE WOULD GO HERE)

If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?

8 pictures

Step-by-step explanation:

Given

Step-by-step explanation:

Determine the number of pictures

First, we need to calculate the length of the available space

This is calculated by subtracting the width of the window from the width of the wall.

Convert fraction to decimal

Since, the pictures are placed side by side.

This means that, there's no empty space between them.

Number of pictures is:

Convert feet to inches

Hence, 8 pictures can fit the wall

the answer is c)8

step-by-step explanaction:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
