Answer:
Area: 6a^2
Perimeter: 12a^2
Step-by-step explanation:
To find the area of a triangle, use the formula A=1/2 b*h. The base is 3a^2 and the height is 4a^2.
A= 1/2 (3a^2)(4a^2)
A = 1/2 (12a^4)
A = 6a^4
To find the perimeter of the triangle, add each of the sides of the triangle. The third side, the hypotenuse, can be found using Pythagorean theorem.

Now add each of the sides: 3a^2 + 4a^2 +5a^2 = 12a^2
Your answer is 21 for this one.
So your equation is

. You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now

You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's

right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be
0.36.
I hope I helped!

Step-by-step explanation:
Answer:
Because f(g(x)) = g(f(x)) = x, f and g <u>are </u> inverse functions.
Step-by-step explanation:
f(g(x)) = f(
) = 
g(f(x)) = g
