Answer:
4x+20
Step-by-step explanation:
Using the distributive property you multiply the terms outside by the terms inside. So the expression will be like this
4(x)+4(5)
When simplified the answer is
4x+20
Divide the area into 6 portions and find the sum of each one to find the value of the final integral:
f(x)dx = 2(8+4)/2 + 1 (8+6)/2 + 2 (6+10)/2 + 1(10+10)/2 + 2 (10+12)/2 + 1 (12+16)/2
= 12 + 7 + 16 + 10 + 22 + 14 = 81 sq units
Answer:
100
Step-by-step explanation:
15 times 6 plus 10 because there is 60 mintues in an hour
First add 15 to both sides:
2n = 68
Then divide each side by two.
n = 34
