Answer:
a square backyard with width (x - 9)
Step-by-step explanation:
x²−18x + 81 = x² - (2 x 9) x + 9² = (x - 9)²
width = area / length = (x - 9)² / (x - 9) = x - 9
Length = width
This is a square backyard
Answer:
$89.1
Step-by-step explanation:
13.5 % of $660
= 13.5/ 100 × 660
= 0.135 × 660
= 89.1
hence, $ 89.1

Answer:
±1, ±11, ±1/5, ±11/5
Step-by-step explanation:
f(x) = 5x³ - 7x + 11
constant term: 11
leading coefficient: 5
factors of the constant term: ±1, ±11
factors of the leading coefficient: ±1, ±5
possible rational roots = factors of the constant term/factors of the leading coefficient = ±1, ±11, ±1/5, ±11/5
There is a total of $35,000 worth of prizes being given out for 5,000 tickets. We can find the expected value for each ticket by dividing 35,000/5,000. This equals $7.00.
