Answer:
4(x-4.5)^2
Step-by-step explanation:
h(x)=4x^2-36x+81
=4(x^2-9x)+81
=4(x^2-9x+20.25)-(4)(20.25)+81
=4(x-4.5)^2
X - 5 = 27
Isolate the x, add 5 to both sides (because of equal sign)
x - 5 = 27
x - 5 (+5) = 27 (+5)
x = 27 + 5
x = 32
x = 32 is your answer
hope this helps
Answer:
7 miles
Step-by-step explanation:
Distance = Rate times Time
Distance #1: (15 mph)(12/60 hr) = 3 miles
Distance #2: (12 mph)(20/60 hr) = 4 miles
Total distance ridden = 7 miles
