Step-by-step explanation:
-2x³ + 14x² + 120x
= -2x(x² - 7x - 60)
= -2x(x - 12)(x + 5).
The other 2 dimensions are -2x and (x + 5).
When using a graphing calculator to maximise the volume of the prism, we get x = 7.378. However this value is not reasonable as it makes -2x and (x - 12) negative, which are the sides of the prism.
Answer: Option 3
Step-by-step explanation:
You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount. You only multiply or divide, never add or subtract, to get an equivalent fraction.

Answer:
C
Step-by-step explanation:
Given
+ 
← factor the denominator of first fraction
= 
+
Multiply the numerator/ denominator of second fraction by (x + 2)
= + 
The denominators are now common, so add the numerators leaving the denominator, that is
= 
= 
→ with numerator 4x + 6 → C
