1) (x − 5)² = (x − 5) (x − 5) = x² − 5x − 5x + 25 = x² − 10x + 25 .
2) (x + 5)² = (x + 5) (x + 5) = x² + 5x + 5x + 25 = x² + 10x + 25 .

Answer:
£151.20
Step-by-step explanation:
20%= 100%divided by 5
To find 100% from 20% you x by 5
so you times 30.24 by 5
30.24x 5 = 151.2
So the answer is £151.20
interest percentage rate would be 1.6754%
160 was the original price.
We know this because 25% is the same as I think of it as a quarter 25x4=100
So you would have to do 40x4=160
Your welcome.
The equation of the function would be:
B. f(x)=4x+4, because if x=2, and if the answer is 12, 12 divided by 2 is 6, so f=6 4 multiplied by 2 is 8 added by 4 is 12. The equation in numbers would be 6(2)=12 or 6(2)=4(2)+4 which ends up being 12=12.
