Step-by-step explanation:
x = 27° (A)
Step-by-step explanation:
5x° + (x + 18)° = 180°
(5x + x)° + 18° = 180°
6x° + 18° = 180°
6x° = 180° - 18°
6x° = 162°
x° = 162 ÷ 6
x° = <u>2</u><u>7</u><u>°</u>
So, the value of x is 27° (A)

Answer:
f(8) = 195
Step-by-step explanation:
When the x if f(x) is replaced with an 8, this just means that it is the eighth term. All you really have to do is replace every X in the function to find the answer.
f(8) = 3 + 3(8)²
f(8) = 3 + 3(64)
f(8) = 3 + 192
f(8) = 195
