Sum of all the angles in a triangle = 180°
(2x + 5) + (6x - 10) + (x + 5) = 180
2x + 5 + 6x - 10 + x + 5 = 180
Combine like terms:
9x = 180
Divide by 9:
x = 20
Answer: x = 20°
(F of g)(x) = f(2x+1) = 8*(2x+1) = 16x + 8 Choice B
Answer:
The amount of money is 60$
Step-by-step explanation:
Given, Principal, P = $40
Rate, R = 10%
Time, T = 5 years
We have to calculate the amount A = S.I + P

⇒ 
= 20
Hence, Amount = S.I + P
= 20 + 40 = 60$
