1 + 5 = 6
1 + 5 = 6
1 + 5 = 6
Answer:
1
Step-by-step explanation:
f(x)=x^3+2x^2-x-1
f(1)=1^3+2(1)^2-1-1
f(1)=1+2*1-1-1
f(1)=1+2-1-1=3-1-1=2-1=1
Whatever was being measured is lower for the second year than it was for the first.
25 × x = 45
or 25÷100 × x= 45
multiplying both sides by 100 and dividing both sides by 25, we have x = 45×100÷25
therefore, x = 180
( if you use a calculator simply enter 45×100÷ 25)
