Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589
Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
Answer:
B
Step-by-step explanation:
Though it is not obvious, the c belongs in the numberator, not the denominator.
So C and D are both wrong.
9: 3 * 3
3: 3
4:2 * 2
Lowest common denominator = 2 * 2 * 3 * 3
Lowest common denominator = 36
B
Answer: Division
Parentheses first according to the order of operations, and the next thing you do is divide inside the parentheses.
<span>Old Surface Area = 202 ft^2
New Surface Area = 1818 ft^2
Notice we have this ratio:
(new area)/(old area) = 1818/202 = 9
and how 3^2 = 9. This is no coincidence.
The old surface area is multiplied by 3^2 = 9 to get the new surface area
.
If you asked "What would the surface area of the prism be if each dimension were quadrupled?"
, then you would multiply the old surface area by 4^2 = 16 to get the new surface area So really thats how you would solve that </span><span />
The answer to this question is D
