Please help me. If u = 5 inches, v = 7 inches, w = 3 inches, x = 6 inches, y = 13 inches, and z = 4 inches, then what is the perimeter of the object?
A. 78 inches
B. 38 inches
C. 45 inches
D. 48 inches

38 inches

Step-by-step explanation: Remember that the perimeter of a figure is the distance around the figure. So we can find the perimeter of this figure by adding the lengths of each of the sides.

So we have

 5 in.

 7 in.

 3 in.

 6 in.

 13 in.

+ 4 in.

38 inches

So the perimeter of this figure is 38 inches.

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.
