The answer for f.f (x) = 25 / 4x² and g.g(x)= 4x² -28x +49.
<h3>What is a Function ?</h3>
A function is a mathematical statement used to relate a dependent and an independent variable.
It is given that
f(x) = 5/2x
g(x) = 2x - 7
It is asked to found
f.f
g.g
f.f (x) = (5/2x) * (5/2x)
= 25 / 4x²
g.g(x)= ( 2x - 7)( 2x - 7)
= 4x² -28x +49
Both the answers are in its simplified form
Therefore the answer for f.f (x) = 25 / 4x² and g.g(x)= 4x² -28x +49.

Answer:
Step-by-step explanation:
The given expresion is:
(−2x + 4y)(3x − 7y)
We expand using the distributive property: (a+b)(c+d)=a(c+d)+b(c+d)
We apply this property to get:
We expand further to obtain:
<u><em>Answer:</em></u>
the answer is he rode 17 miles in the morning and 40 miles in the afternoon
<u><em>Step-by-step explanation:</em></u>
so in the afternoon, it says that 6 more than twice as many miles in the afternoon as in the morning. this means that if the morning is x then in the afternoon it will be 2x+6 but it says altogether it is 57 miles so the you have to add x too.
so the equation is 2x+6+x=57
then this should be easy to solve.
2x+6+x=57
3x+6=57
3x=51
x=17
so if the morning is 17 miles then the afternoon will be:
2(17)+6
this equals to 40.
I hope that this is helpful!
