Answer:
Step-by-step explanation:
We want to factor
First, we factor the GCF to get:
Now, we rewrite the expression in the parenthesis as difference of two squares.
Recall that:
We apply this property to get:
Therefore the completely factored form of the given expresion is:
We can set up a proportion with the information:
=
where x = the miles the train travels in 13 hours.
Now solve for x; multiply the numerator of the first fraction by the denominator of the second fraction and vice versa, and set them equal to each other:
240 · 13 = 5 · x
3120 = 5x
Finally, use the Division Property of Equality to divide both sides by 5 and find the value of x:
624 = x
Therefore, the train travels 624 miles in 13 hours.

A. y = 1/3 (-3) - 3 = - 6
B. y = 2(-3)^2 - 3(-3) - 2
= 2(9) - 3(-3) - 2
= 18 + 9 - 2
= 25
C. 2(-3) - 5y =4
- 6 - 4 = 5y
y = - 2
