Answer: T(x) = 18x + 65
Step-by-step explanation:
T(x) = A(x) + B(x)
T(x) = 10x + 50 + 8x + 15 [Plug in the number for A(x) and B(x)]
T(x) = 10x + 8x+ 50 + 15
T(x) = 18x + 65
x/4 = 3/2
x/2 = 3 (multiply both sides by 2)
x = 6 (multiply both sides by 2)
Therefore 6/4 = 3/2
That's a pretty confusing one. I think it's 10 minutes.
If this is talking about the Pythagorean theorem then it would be 5,12,13 becuase because the equation for the triangle is
2 2 2
a + b = c
2 2 2
5 + 12. = 13
