Answer:
48
Step-by-step explanation:
base times hight times times 1/2
24X4X1/2
F(x) = -3x - 2
f(-5) = -3(-5) -2 = 15 - 2 = 13
Answer:
35 mph
Step-by-step explanation:
time = distance / speed
210 miles and has an average of a certain speed
t = 210 / s
If the average speed had been 3mph more, he could have traveled 228 miles in the same length of time
t = 228 / (s + 3)
Set equal
210 / s = 228 / (s + 3)
Cross multiply
210s + 630 = 228s
Subtract 210s from both sides
630 = 18s
Divie both sides by 18
35 = s
35 mph
