2) Suppose youwere hired to estimate replacing the shingles on a sloping roof (shaped like an upside-down "V"). You have some long sticks and a tape measure, but no ladder. You must buy complete bundles of shingles. Here are some measurements you have taken:

The distance from the ground to the top of the roof is 20 feet.

The distance from the ground to the horizontal bottom of the roof is 15 feet.

The distance from the vertical left side of the roof to the vertical right side of the roof is 42 feet.

The length of the house is 102 feet.

The cost of shingles is $23.15 per 33 1/3 sq. ft. bundle.

Select one:

A.

$1,529.20

B.

$3,058.40

C.

$3,078.95

D.

$1,539.48

3) Use the discriminant of the quadratic formula to determine the type and number of solutions to the equation:

216x² - 512 = 0

Select one:

A.

Two equal, real solutions.

B.

Two unequal, complex solutions.

C.

Two equal, complex solutions.

D.

Two unequal, real solutions.

4) How would you write the following equation algebraically, using one variable:

What are two numbers, such that the sum of them is 10 and the product of them is 10?

Select one:

A.

x+ (10 - x) =x (10 -x)

B.

x+ (x - 10) = x (x - 10)

C.

x+ (x + 10) = x (x + 10)

D.

x+ 10 = x (10)

E.

x + y = x (y)
