Answer:
-6m-12
Step-by-step explanation:
-(2m-7)-(3+4(m+4)) =
-2m+7-(3+4m+16)=
-2m+7-(19+4m)
-2m+7-19-4m
-6m-12
OR:
-m-2 ( if you divide by 6 as a common factor)

b. List all possible rational roots.
c. Use synthetic division to find the roots of the polynomial equation. Are the roots all rational numbers?
d. What are the dimensions of the storage compartment?
I really only need a. and d. though, thanks.
We start with f(0) = 2, we can use this value to find out the next value f(1) in our relation.
f(1) = -2 f(0)+3 = -2(2) + 3 =- 4 +3 =-1 Now we know f(1) we can work out f(2):
f(2) = -2 f(1)+3 = -2( -1)+3 = 2 +3 = 5.
So f(2) = 5
Answer:
5%
Step-by-step explanation:
1. We assume, that the number 48 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 48, so we can write it down as 100%=48.
4. We know, that x% equals 2.4 of the output value, so we can write it down as x%=2.4.
5. Now we have two simple equations:
1) 100%=48
2) x%=2.4
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=48/2.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 2.4 is what percent of 48
100%/x%=48/2.4
(100/x)*x=(48/2.4)*x - we multiply both sides of the equation by x
100=20*x - we divide both sides of the equation by (20) to get x
100/20=x
5=x
x=5
now we have:
2.4 is 5% of 48
