Answer:
The family will pay 34722 cents more if they take the van
Step-by-step explanation:
Given
Van = 12 miles per gallon
Sedan = 36 miles per gallon
Distance = 2500 miles
Gas = $2.50 per gallon
First, we need to determine the number of gallons that'll be used by both vehicles
This is done by dividing total distance by number of miles per gallon


Next, is to multiply this by the cost of gas per gallon;
This gives the total spendable amount on both vehicles






Next is to get the difference between these amounts


Multiply by 100 to convert to cents


(Approximated)
Hence;
<em>The family will pay 34722 cents more if they take the van</em>
2,8 is the Awnser if you can see it on the graph it goes 2 up 8 right
Answer:
x = −10 and x = 4
Step-by-step explanation:
x2 + 6x = 40
Subtract 40 from each side
x^2 + 6x -40 =0
Factor, what 2 numbers multiply to -40 and add to 6
10 * -4 = -40 10+-4 = 6
(x+10) (x-4) = 0
Using the zero product property
x+10 =0 x-4=0
x=-10 x=4
