5x^2+10x
factorise 5 and 10 first
then factorise the x
so 5x(x+2)
completed :))
hope this helped :)
Answer:
p1= 95, p2 = 180
Step-by-step explanation:
We have population : 50 given that population grows by 90% per year
So, After one year: new population (p1) will be
p1 = 50 + 50*0.9 = 50 + 45 = 95
Now, After two years: new population (p2) will be
p2 = 95 + 95*0.9 = 95 + 85.5 (approximately = 86) = 95 + 86 = 180
Therefore,
p1 = 95, and p2 = 180.
Answer: f(2) = -4
Step-by-step explanation: Here we're given the function f(x) = -3x + 2 and we are asked to find f(2).
In other words, if we put an <em>x</em> into our function, we get a -3x + 2 out so what happens when we put a 2 into the function?
Well if we put a 2 into the function,
that's f(2) and we get -3(2) + 2 out.
Now all we have to do is simplify on the right side.
-3(2) is -6 so we have -6 + 2 which is -4.
So f(2) is -4.
Well in my answer i got 5.06 i rounded to the nearest hundred instead of putting all of the numbers behind the 6.
