Answer:
6
Step-by-step explanation:
f(x) = 4x - 6
g(x) = √ x+2
so we have that:
(fºg)(x) = 4( √ x+2)- 6
(fºg)(7) = 4( √ 7+2)- 6
(fºg)(7) = 4( √ 9)- 6
we know: √ 9 = √ 3^2 = 3
we have:
(fºg)(7) = 4(3)-6
(fºg)(7) = 12-6
(fºg)(7) = 6
Please, post the instructions along with your question, and if possible share the question in symbolic form, not in words.
Do you mean Question #5? By (2) x cube, do you mean 2x^3?
I strongly suggest that you use lots of parentheses ( ) to show how your numbers are grouped, and not to use " x " to denote multiplication (use " * " for that, please.
If only you'll clear this up, I'd be happy to help.
I will assume that your post is 2x^3 - 3(9x-5)^2.
Then 2x^3 - 3(81x - 90x + 25). Does this have any resemblance to what you wanted me to see in your post?

Answer:
x<3. Hope this helps!
Step-by-step explanation:
B=2h-7
Area of a triangle: A=1/2 of bh
replace b with 2h-7: A=(1/2)(2h-7)h=102 => (2h-7)h=204
2h^2-7h-204=0
factor or use quadratic function to solve
h=12
b=2*-7=17
