Answer:
4x + 18
Step-by-step explanation:
This is called a composite function, meaning passing the range of one function as a domain of another function.
For f(f(x)), the inner-function's range is passed as the domain of the outer function.
We can do so by substitution,
The range of f(x) can be written as 2x + 6 for any defined x values,
So we will substitute 2x + 6 as the 'x' of another function which is in this case
f(x) again, so it looks like this 2(2x+6) + 6 which can be simplified into
4x + 18
Answer:
6
Step-by-step explanation:
The legs of an isosceles triangle are 7cm longer than the base. Find the legs if the perimeter of the triangle is 38cm.
(38 - 7 - 7) : 3 = <em>8 cm (base)</em>
8 + 7 =
<h2><u><em>
15 cm ( Legs)</em></u></h2>
check
8 + 15 + 15 = 38
the answer is good
