Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- algebraic identity:(a-b)²=(a+b)²-4ab
<h3>let's solve:</h3>
therefore
using the identity our answer is (a-b)²
let's prove it
- (a-b)²:a²-2ab+b²
- rewrite -2ab as 2ab-4ab:a²+b²+2ab-4ab
- use (a+b)²=a²+2ab+c²:(a+b)²-4ab
therefore
we have also proven that

1.5×2.5=
I will put the answers in the comments I need to use a calculator
Hello from MrBillDoesMath!
Answer:
No
Discussion:
If the functions are inverses, then f(g(x)) = x for appropriate x. Consider x = 1.
g(1) = 1/ (5(1) + 1) = 1/6
f(g(1)) = f (1/6) = 5(1/6) + 1/ (1/6) = 5/6 + 6 = 6 5/6 <> 1
Conclusion: f(g(1)) <> 1 so the functions are not inverses
Thank you,
MrB
The answer is 7, hope it’s right
