For this question, all you have to do is combine like terms. I am assuming that the 3x2 and 5x2 are exponents, so they are one pair and then -4x and 8x are the other. The rule is the higher exponent goes first, so here is what it looks like:
3x2 - 4x - 5x2 +8x
First combine the numbers with exponents, 3x2-5x2, you always bring over the positive or negative, which ever it may be, in this case, since it is -5x2, you bring that over.
3x2-5x2=-2x2
Now to do the number with matching letters, -4x+8x= 4x
Now just bring the problem back together:
-2x2+4x
That is your simplified answer: -2x2+4x.
No, to be perpendicular the lines would have to be straight.
Hope it helped! :)

Step-by-step explanation:
6 is equal to 42/7, and 3 and 5/7 is 26/7 so 42-26 = 16/7 which is also 2 and 2/7 ths
Answer:

Third Answer:
$3.27.
Step-by-step explanation:
First Question:
Cost of the rented car = 50 + 0.20 = $50.20
How much did Matt's family spend for the car:
1 mile = $50.20
300 miles = ?
300 × 50.20
= $15,060.
Second Question:
If Hayden spent $500 for her rented car, how many miles did she drive:
$50.20 = 1 mile
$500 = ?
500 ÷ 50.20 = 9.96 miles.
Third Question:
What is the cost per gallon of gas:
24 gallons = $78.48
1 gallon = ?
78.48 ÷ 24 = $3.27.
