Answer: LAST OPTION.
Step-by-step explanation:
To solve this exercise is important to remember the following definitions:
- The sum is the result obtained when we solve an addition.
- The product is the result obtained when we solve a mutiplication.
- Given a multiplication
, "a" and "b" are factors and "c" is the product.
In this case, you have this expression:
Notice that the there is an addition of two terms (
and 
) inside the parentheses.
Outside the parentheses you can notice that the number 
is multiplying the sum of the terms mentioned before.
Therefore, you can conclude that the best description for this expression is:
<em>The product of a constant factor of seven and a factor with the sum of two terms.</em>
3/4 - 2/3
3/4 × 3 = 9/12
2/3 × 4 = 8/12
9/12 - 8/12 = 1/12
Tom's score is 1/12 because in order to find his score, you'll have to subtract. So you have to subtract 3/4 - 2/3 but you can't subtract it since they don't have a common denominator. What you have to do to find the common denominator is to find the least common denominator by finding a multiple of 4 and 3. I know that 4 × 3 = 12 and 3 × 4 = 12, so that is gonna be my denominator. Now, we just have to multiply 3/4 by 3 and 2/3 by 4 and we have the answers of 9/12 and 8/12. Now I can subtract. 9/12 - 8/12 is gonna equal 1/12. This shows how I got my answer of 1/12.

GRAPH ALL THREE COORDINATES AND DRAW LINES TO SEE WHERE IT INTERSECTS
If the wall is 100%=1, then Stan paints x percent of the wall in 15 minutes and Ted paints (1-x)=y percent of the wall in 15 minutes due to that they finish the wall in 15 minutes. Assuming Stan paints the wall at a uniform rate, he gets 15/40=3/8=0.375 of the wall done in 15 minutes, meaning that Ted paints 1-0.375=0.625 of the wall in 15 minutes. We want to know how long it takes for himself to get the wall done, so we have that if Ted finishes the wall in z minutes, 0.625/15*z=1 (since 0.625/15 is how much he gets done in 1 minute). Dividing both sides by (0.625/15), we get z=15/0.625=24
F(x) +G(x) +H(x) = (2x -1) +(3x +2) +(x²)
