Step-by-step explanation:
A. The difference of twice the cube of a number and 11
I have the same problem with you
All you have to do is replace every x with 2 and then solve:
<em>Make to sure to follow the Order of Operations!!</em>
-9x(2) + 11x - 7 =
(-9 × 2 × 2) + (11 × 2) - 7 =
-36 + 22 - 7 =
-14 - 7 =
-21
The answer is -21.
Hope that helps!
Answer:
223.5 Km
Step-by-step explanation:
Area = Length x Width
Solving for Square Shape
8 · 6 = 48 km
Area = Length x Width
Solving for Rectangle Shape
9 · 14 = 126 km
Area = Length x Width ÷ 2
Solving for Triangle Shape
11 · 9 = 99 ÷ 2 = 49.5 Km
48 + 126 + 49.5 = 223.5 Km
First, let’s plug in our x and y values.
3|-2(6) - 4|
simplify the inside of the absolute value brackets
3|-12 - 4|
3|-16|
Since the absolute value of -16 is 16, the equation looks like this:
3(16)
48.
The answer is D. 48
