A tent company has a tent design that is a triangular prism. The following is a net of the design. Note: Figure is not drawn to scale.
Substitute your variables for numbers

If a = 70 inches, b = 71 inches, c = 56 inches, and d = 64 inches.

How much fabric is needed to make the tent?

Image result for calculator Make sure to use a calculator and check your work.

Select one:
A. 17,920 sq in
B. 24,850 sq in
C. 14,336 sq in
D. 17,500 sq in

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

step-by-step explanation:

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.
