Answer:
the sum of triangle is 180°
(2x-15)+(x-5)+42°=180°
2x+x-15°-5°+42°=180°
3x+22°=180°
3x=180°-22
3x=158°

Answer:
f(x) = -4
Step-by-step explanation:
Given function: f(x) = 4 + 4x - 4x²
Here, we are being asked to find the value of the function when x is equal to 2.
Substitute 2 as the value of x in the function and simplify:
⇒ f(x) = 4 + 4x - 4x²
⇒ f(2) = 4 + 4(2) - 4(2)²
⇒ f(2) = 4 + 8 - 4(4)
⇒ f(2) = 4 + 8 - 16
⇒ f(2) = 12 - 16
⇒ f(2) = -4
This means that when the value of x is 2, the value of the function is -4.

Is there any context to this question?
Let's represent the number of sodas with 's' and the number of hot dogs with 'd':
s = 2d
s + d = 123
2d + d = 123
3d = 123
divide:
d = 41
123 - 41 = 82
The vender sold 41 hot dogs and 82 sodas
