hi
f°g mean apply g(x) and then use result of g(x) as "x" in f(x)
so as g(x) = x² +1 and f(x) = 3x+2
so if we call g(x) X we have
f( X) = 3 X +2
now we replace " X" for it's value
f(X) = 3 ( x² +1) +2
f(X) = 3x² +3 +2
f(X) = 3x² +5
so f°g = 3x² +5

<em><u>The surface area of cylinder in standard form is:</u></em>

<em><u>Solution:</u></em>
Given that,
Radius of cylinder = 2x + 3 inches
Height of cylinder = 3 times radius = 3(2x + 3)
Height of cylinder = 6x + 9 inches
<em><u>The surface area of cylinder is given by formula:</u></em>

Where, "r" is the radius and "h" is the height of cylinder
<em><u>Substituting the given values we get,</u></em>

Thus the surface area of cylinder in standard form is found

Answer:
x ≤ 15
Step-by-step explanation:
2x + 20 - 20 ≤ 50 -20
2x ≤ 30
2x/2 ≤ 30/2
x ≤ 15
