First, replace all variables with the given values.
12(9) + 9(2) + 2(12)
This should then equal 150, then the formula says to multiply this answer by 2. Doing so, should give a final answer of 300.
Answer:
C on edge 2021
Step-by-step explanation:
No. 0.2487 is not an interger.
There are two big reasons for this:
1). There is no such thing as an ' interger ',
so no number could be one.
You probably mean ' integer '.
2). An integer is a whole number ... a number
with no fraction part and no decimal part.
0.2847 is all decimal, and not even big enough
to make the smallest whole number. (That's ' 1 '.)
(3x - 2)^2 is the same as:
(3x - 2)(3x - 2)
use the FOIL method: First, Outside, Inside, Last
3x(3x) = 9x²
3x(-2) = -6x
-2(3x) = -6x
-2(-2) = 4
9x² - 6x - 6x + 4
Combine like terms
9x² (- 6x - 6x) + 4
9x² - 12x + 4 is your answer
hope this helps
