I am from Bulgaria so can they add a bulgarian vertion
A (t - 15)(t + 2)
b (w + 3)(w - 18)
c (2n - 1)(x + 2)
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.
Answer:
Step-by-step explanation:
a)L=2w+4
b)P=2L+2w
sub L=2w+4,
P=2(2w+4)+2w
P=4w+8+2w
P=6w+8
c) 20=6w+8
12=6w
2=w
L=2(2)+4
=8
Hence,
L=8 and w=2
