A. (f + g)(x) = f(x) + g(x) = 4x - 5 + 3x + 9 = 7x + 4
B. f.g (x) = f(x) * g(x) = (4x - 5)*(3x + 9) = 12x^2 + 36x - 15x - 45
= 12x^2 + 21x - 45
C Replace the x in f(x) by g(x):-
= 4(3x + 9) - 5
= 12x + 36 - 5
= 12x + 31
Answer:
All pair COMBINATION are supplementary (Opposite)
Step-by-step explanation:
According to theorem about inscribed quadrilateral
- The opposite interior angles of an inscribed quadrilateral are supplementary .
- I.e there sum is equal to 180°
<O+<Q=180
<P+<R=180
They equal to 180 because they are supplementary angles

Question:
The tank for a car holds 17 gallons. The gasoline gauge shows the tank is 3/4 full. How much gas is still in the tank?
Give your answer as a whole number or as a mixed fraction reduced to lowest terms.
Answer:
Step-by-step explanation:
The tank for a car holds 17 gallons.
The gasoline gauge of the car shows that the tank is 3/4 full.
We are asked to find the remaining gasoline in the tank.
Therefore, the remaining gas in the tank is gallons.
Alternatively:
Amount of gasoline consumed =
Amount of gasoline left = total - consumed
Amount of gasoline left =
