G(x) = 3x² - 5x + 7
b) g(-2) ==> Substitude -2 into x
g(-2) = 3(-2)² - 5(-2) + 7
g(-2) = 12 + 10 + 7
g(-2) = 29
c) g(4) ==> Substitude 4 into x
g(4) = 3(4)² - 5(4) + 7
g(4) = 48 - 20 + 7
g(4) = 35
d) g(-x) ==> Substitude -x into x
g(-x) = 3(-x)² - 5(-x) + 7
g(-x) = -3x² + 5x + 7
e) g(1 - t) ==> Substitude 1 - t into x
g(1 - t) = 3(1 - t)² - 5(1 - t) + 7
g(1 - t) = 3(1 - 2t + t²) - 5 + 5t + 7
g(1 - t) = 3 - 6t + 3t² - 5 + 5t + 7
g(1 - t) = 3t² - t + 5
it costs 8 dollars to rent a locker because
28x5=140
180-140=40
40/5= 8
The average speed would be 53 miles per hour, hope this helped, if you need me to explain then here is the way, so all you do is divide 265 by 5 and what I did to help make it faster was split 265 into 250 and 15 so 250 divided by 5 is 50 and 15 divided by 5 is 3 so 50 + 3 = 53!
The area of a trapezoid is (a+b)/2 * h
a is the length of the small base which is the one on the top and is 4cm
b is the length of the big base which is the one at the bottom and is 4 + 3 + 3 = 10cm
h is the height which is 7cm
So the area is (4+10)/2 * 7
A= 14/2 * 7
A= 7 * 7
A= 49 cm^2
Answer is B. Have a nice day.
