Triangle has a total of 180 degrees
add up all angles
A+B+C = 3x+5+4x-2+2x+6=180
9x=171
x=19
Plug x values into the A , B and C expressions and you get your answers
X^2+2x-5x-10
x(x+2)-5(x+2)
(x-5)(x+2)
3.08 is the answer because:
1(1)+3(2)+4(3)+4(4)+1(5)=40
40/13 is about 3.08.
Answer:

Step-by-step explanation:
You would substitute "2x" for every "x" in the function in the same way you would substitute any other number.
So if f(x)=Sqrt[7x²-3x], then: f(2x)=Sqrt[7(2x)²-3(2x)]
=Sqrt[7(4x²)-3(2x)]
=Sqrt[28x²-6x]
