Answer: 4^x+5x-2</h3>
Add up the equations and combine any like terms. In this case, the like terms are -8 and +6 which combine to -2. Everything else is unlike terms so you leave them as is.
f(x) + g(x) = (4^x-8) + (5x+6)
f(x) + g(x) = 4^x + 5x + (-8+6)
f(x) + g(x) = 4^x + 5x - 2
Time=distance/speed
621÷51.75
=12
So it takes 12 hours
Answer is 17.647 or if rounded 18
Answer:
x = 27
Step-by-step explanation:
(whole secant) * (external part) = (tangent)^2
(x+48)* 48 = 60^2
(x+48)* 48 = 3600
Divide each side by 48
x+48 =75
Subtract 48 from each side
x = 75-48
x=27
