Answer:

$\boxed{\sf x=2}$

Step-by-step explanation:

$\sf 2x+5=9$

Subtract 5 from both sides.

$\sf 2x+5-5=9-5$

$\sf 2x=4$

Divide both sides by 2.

$\sf \cfrac{2x}{2}=\cfrac{4}{2}$

$\sf x=2$

Hello from MrBillDoesMath!

Answer: 21

Discussion:

g(3) = 3^2 -2 = 9 -2 = 7 =>

f(g(3)) = f ( 7) = 2(7) + 7 = 14 + 7 = 21

Thank you,

Some 1 plz HELP! 3 5/6 X 4 4/5 (plz include instructions if u can thx!)

rewona [7]

Well convert 3 5/6 to 23/6 and 4 4/5 to 24/ 5
then find a multiple that both 5 and 6 have which is 30
23x5= 115 and 24x6= 144
so 115 x 144= 16560/30
16560/30 = 552 /1 so your answer is
552
