You do 153 ÷ 18 = 8.5, and because you can't have 0.5 of a CD, the answer is 8. Hope this helps!
Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)
A. 14 + 2 × 5 = 14 + 10 = 24 ≠ 22
B. (14 + 2) × 5 = 16 × 5 = 80 ≠ 22
C. 24 - 6 ÷ 3 = 24 - 2 = 22
D. (24 - 6) ÷ 3 = 18 ÷ 3 = 6 ≠ 22
<h3>Answer: C.</h3>
The surface area of the cylinder is 301.44
STEP-BY-STEP SOLUTION:
= x^2 - 13x + 30
= x^2 - 10x - 3x + 30
= x ( x - 10 ) - 3 ( x - 10 )
= ( x - 10 ) ( x - 3 )
FINAL ANSWER:
Therefore, the answer is:
C. x - 10
