Answer:
B.
Step-by-step explanation:
Simplify the expression. Remember to go by the order of operations, or PEMDAS.
1) First, distribute the numbers outside of the set of parentheses to the terms inside the set of parentheses next to them. Then, simplify the fractions.
2) Finally, combine like terms. (This means to add or subtract constants and to add or subtract terms with the same variables.) You may need to convert terms to the same denominator in order to do so easier. Then, reduce the fraction.
Thus, the answer is .

Answer:
the solid color fleece is a better price
Step-by-step explanation:
Data:
Solid color fleece: S
Paterned fleece : P
Cost:
S=$1649 per 6 yards
P= $15.40 per 16 feet
To find which fleece is better price you need to find the price of each one per the same unit.
1. Turn the yards in feet (1 yd is equal to 3 feet )
2. Find the price per 1 feet of each fleece:
Solid color fleece: $ 0.916 per 1 feet
Patterned fleece: $0.9625 per 1 feet
Then, the solid color fleece is a better price

Answer:
f(x) = + 8x² - 9
Step-by-step explanation:
Given the zeros of a polynomial say x = a and x = b, then
the corresponding factors are (x - a) and (x - b)
The polynomial is the the product of the factors
f(x) = (x - a)(x - b)
Given zeros x = 1, x = - 1, x = 3i and x = - 3i, then corresponding factors are
(x - 1), (x + 1), (x - 3i) and (x + 3i), then
f(x) = (x - 1)(x + 1)(x - 3i)(x + 3i) ← expand in pairs using FOIL
= (x² - 1)(x² - 9i²) → note i² = - 1, thus
= (x² - 1)(x² + 9) ← distribute
= + 9x² - x² - 9 ← collect like terms
= + 8x² - 9
