Answer:
<h2><u><em>
2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u></h2>
Step-by-step explanation:
Write an expression for the perimeter of a rectangle with a length of
(3x² + x + 2) and a width of (-x² – 5x + 1).
P = 2 × (L + W)
<u><em>2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u>
if you want the result:
4x²−8x+6
<u>Given</u>:
The given expression is 
We need to determine the exponents in simplified form.
<u>Exponents in simplified form:</u>
Let us determine the exponent in simplified form.
Let us apply the exponent rule 
Thus, we have;
Adding the fractions, we get;
Cancelling the common terms, we have;
Simplifying the exponent, we get;
Adding the exponent, we have;
Thus, the simplified form of the expression is
Answer:
hello : f(h(g(x)))= (4x - 9) + 4 /(4x - 9)
Step-by-step explanation:
calculate : h(g(x))
h(g(x)) = h(x - 2) = 4 (x -2) -1 = 4x - 8 -1
h(g(x)) = 4x - 9
calculate : f(h(g(x)))
f(h(g(x))) = f (4x - 9) = (4x - 9) + 4 /(4x - 9)
