Answer:
17.5
Step-by-step explanation:
simple first we find the miles per gallon
so 300/15=20 therefor he would only need a extra 3 gallons to go 360 miles so your answer is
B.18
Answer to problem 1 is (9,9)
Answer to problem 2 is (0,-4)

Explanation:
To find the component form, they basically want the translation rule. To find the translation rule, we subtract the coordinates tip - head
In general, if we have two vectors M and N such that
M = (a,b)
N = (c,d)
then
vector MN = (c-a, d-b)
Applying this to the vector CD gives us
vector CD = (7-(-2), 10-1) = (7+2, 10-1) = (9, 9)
Basically meaning that we shift point C nine units to the right and nine units up to get to point D
Similarly,
vector RS = (-4-(-4), -3-1) = (-4+4, -3-1) = (0,-4)
so we shift point R four units down to get to point S
The binomials needed to be factored are examples of perfect square binomials, so the factors should contain the square root of the expressions inside the binomial. The pairs are,
,
,
, the last one is a bit tricky because its factors still has a common factor that can be taken out and it is,
