Answer:
Step 2: 47
Step 3: 84
Step 4: 114
Step-by-step explanation:
Step 2: The width is 21, and the length is 36.
Sum is addition, so it would be 21 + 36.
21 + 36 = 47
Step 3: 47 x 2 = 84
Step 4: Perimeter is all around, whilst area is on the inside. The length is 21, so it is 21 + 21. 21 + 21 is 42. The width is 36, so it is 36 + 36, which is 72. 72 + 42 = 114.

(3x^2 - 2x)(x + 4)
<em><u>First step would be: distributive property.</u></em>
3x^3 + 12x^2 - 2x^2 - 8x
<em><u>Combine like terms.</u></em>
3x^3 + 10x^2 - 8x is the simplified form of the functions multiplied.
Your answer is D.
Answer:

Step-by-step explanation:
<u>Inequalities</u>
To solve the inequality:

We need to perform the required operations on both sides of the inequality to have the variable w isolated.
First, we subtract 9:


Subtracting 6w:

Operating:
-7w>-1
Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:

Operating:

Solution:

That means there is about 38 fuels in each row because 454 divided by 12 = 37.83333333333333333 (exact number)
