132 inches is the correct answer.
3 yards equals 9 feet. 9 feet plus 2 feet is 11 feet. 11 feet times 12 inches per foot equals 132 inches.
X^3-1 rewrite as x^3-1^3
differences of cubes formula: a^3-b^3=(a-b)(a^2+ab+b^2)
a=x, b=1
(x-1)(x^2+x*1+1^2)
(x-1)(x^2+x+1)
-(5x+4)
-5x + (-1)(4)
-5x-4, so D
Note: -(a+b) = -1(a+b) =-a -b
Answer:
There are 21.4285714 (21 or 22) questions
Step-by-step explanation:
15 / 70% = 21.4285714
21.4285714 * 70% = 15
21 * 70% = 14.7
22 * 70 = 15.4
Both 14.7 and 15.4 round to 15
