Answer:
f(-3) = 16
Step-by-step explanation:
Given:
f(x) = 2x² + x + 1
Required:
f(-3)
Solution:
Substitute x = -3 into f(x) = 2x² + x + 1
f(-3) = 2(-3)² + (-3) + 1
f(-3) = 2*9 - 3 + 1
f(-3) = 18 - 3 + 1
f(-3) = 16
Answer:
64
Step-by-step explanation:
N/100*260=39
260n=3,900
n=3,900/260
=(390*10)/(26*10)
=390/26
=15
39 is 15% of 260.
The answer is quite simple the question is more so as 6·y = 144
so rather do 144÷6 which would equal 24
