(5s+2)(s-3) as writing it as 5s^2-15s+2s+6 is the same as the last form. But makes it easier to factorise as there are common factors.
Answer:
16
Step-by-step explanation:
First, we plug in -3 in place of x...
f(x) = 2(-3)^2 + (-3) + 1
Then, we simplify each indidvidual expression...
f(x) = 18 - 3 + 1
Finally, we add/subtract all the values to get our answer...
f(x) = 16
Answer:
20925
Step-by-step explanation:
multiply 675 by 11 to get 7425. Add 7425 to 13500 to get 20925. To check minus 20925 by 7425. I got 13500. So this answer is reasonable.
