Answer:
x³ - 3x² - 9x + 27
= x²(x - 3) - 9(x - 3)
= (x² - 9)(x - 3)
= (x -3)(x + 3)(x - 3)
= (x + 3)(x - 3)²
Step-by-step explanation:
Answer:
495 in
Step-by-step explanation:
The formula for the volume of a triangular prism is V =
· w · h · l, where w represents with, l represents length, and h represents height. Using this and plugging in the values, we can solve.
V =
· 5 · 11 · 18
V = 2.5 · 11 · 18
V = 27.5 · 18
V = 495
hope this helps :)
Answer:
y = (1/2)x - (15/2)
Step-by-step explanation:
goal: to rearrange the expression such that it is in the form
y = f(x); where f(x) is an expression in terms of x
given:
x - 2y = 15 (subtract x from both sides)
-2y = 15 - x (multiply both sides by -1 to make left side positive)
2y = -15 + x (divide both sides by 2 and rearrange)
y = (1/2)x - (15/2)
It actualy gives you the minimum of the function
it helps you because fonding the minimum y will give you the range
