F(x)=25-x^2
g(x)=x+5
f/g(x)=(25-x^2)/(x+5)
f(x) is in binomial form so 25-x^2 can also be written as (5-x)(5+x)
so
f/g(x)=(5-x)(5+x)/(x+5)
f/g(x)=5-x
162 / 2 = 81
the answer is D
You combine like terms like 8y+13y which gives you 21y and don't forget the -5x so your simplified equation would end up being A. 21 - 5x
question a is 80
question b 20 (is what I could find but not completely sure)
Given :
Mo spends £15 on ingredients to make 40 cookies.
He sells all 40 cookies for 50p each.
To Find :
The Mo's percentage profit.
Solution :
We know, 1 £ = 66.09 p.
So, total income is :
T = 40 × 50 p
T = 2000 p
T = £2000/66.09
T = £30.26
So, total profit is, P = £( 30.26 - 15 ) = £15.26 .
Hence, this is the required solution.
