Question 2
5.2 km/1 day =78.2 km/x days
Multiply both sides by x
5.2x=78.2
divide by 5.2
x is approximately 15.038
or 15 days

Answer:9x6−156x5+664x4+176x3−620x2−48x+144
Step-by-step explanation:
Simplify f(g(x))=-3(2x-3)^2 -2(2x-3)+1
Step-by-step explanation:
you plug in the g(x) function for every x in the f(x) function and then simplify to get the answer. sorry I can't solve it right now
Answer:
x = 20
Step-by-step explanation:
x° + 2x° + (x+10)° = 90°
3x° + x° + 10° = 90°
4x° + 10° = 90°
4x° = 90°-10°
4x° = 80°
x = 80/4
x = 20
