Answer:
f(-2) = 21
Step-by-step explanation:
Step 1: Define
f(x) = 3x² - 4x + 1
f(-2) is x = -2
Step 2: Substitute and Evaluate
f(-2) = 3(-2)² - 4(-2) + 1
f(-2) = 3(4) + 8 + 1
f(-2) = 12 + 9
f(-2) = 21

Answer:
90 minutes
Step-by-step explanation:
Assuming the time is proportional to the number of pages, you have ...
time/pages = 20/6 = T/27
Multiplying by 27 gives ...
T = 27(20/6) = 90
It is expected to take 90 minutes to check 27 pages.
Answer:

Answer:
Step-by-step explanation:
Since the bases are different, each expression must be done independently.
6.7*10^8
6.7*6.7*6.7*6.7*6.7*6.7*6.7*6.7= 4,060,676.78
1.2*10^2
1.2*1.2= 1.44
multiply the two= 5847374.56
