Answer:
C: 1
Step-by-step explanation:
4x^2-4x=24
Subtract 24 from each side
4x^2 -4x -24 = 24-24
4x^2 -4x-24 =0
Factor out a 4 from each side
4(x^2 -x -6) =0
What 2 numbers multiply to -6 and add to -1
-3*2 = -6
-3 +2 =-1
4(x-3) (x+2) =0
4(x-3) (x- -2) =0
p=3 q =-2
p+q
3-2

Answer:
<u>The cost per gallon is US$ 1.87</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Number of gallons of gas = 13
Cost of the gallons of gas = US$ 24.31
2. What is the cost per gallon?
Cost per gallon = Cost of the gallons of gas/Number of gallons of gas

Answer:
A = 800( 1.075)^(t)
Step-by-step explanation:
The equation for interest is
A = p (1+r/n) ^ nt where p is the principle, r is the interest rate, n is the number of times per year and t is the years
A = 800( 1+ .075/1)^(1*t)
A = 800( 1.075)^(t)
Answer:
30 SQUARE units
