Answer:
60
Step-by-step explanation:
so you have a rectangle that has the lengths of 5 and x+2 and x is equal to 10, you add 10 and 2 and get 12 then you do 5 times 12 and get 60.
5(x+2) x=10
10+2=12
5x12=60
4/12 can both go into 4. 4 divided by 4 is obviously 1, so the numerator is 1.12 divided by 4 is 3 so the denominator is 3.
The answer is 1/3 or D
Answer:
f(x) = 2x
Step-by-step explanation:
Remark
What I'm about to do is probably not the best way to do this question, but it is right. The plan is to take out a common factor on the right of f(x - 2) and then derive f(x) from that.
Solution
- f(x - 2) = 2x - 4 Take out a common factor on the right of f(x -2)
- f(x - 2) = 2(x - 2) Now what that means is that in the original equation, wherever you saw an x, you put in x - 2. So the original equation must have been
Check
- f(x) = 2x To check this put x - 2 back in
- f(x - 2) = 2(x -2) Remove the brackets.
- f(x - 2) = 2x - 4 which is what it should be.
