If f(2) = 22 – 5, then what is the value of f(2) + f(5)?
jasenka [17]

Answer:

67

Step-by-step explanation:

With the information of f(2) = 22-5,  you can assume the equation will be f(x) = 11x-5. Using this, you can calculate f(5) by doing 11(5)-5, which is 50. 22-5 is 17, so 50+17=67

Igoryamba

Answer: Jan now has 27 model airplanes.

Step-by-step explanation: The starting figure is 25 model airplanes and this year she has 32% more than she started with. We shall first find out how many that turned out to be. Let the current number of model airplanes be X.

X = 25 + 32%

[To calculate 32% of 25

25 x 32/100

(25 x 32)/100

800/100

8]

X = 25 + 8

X = 33

Now she has 33 model airplanes and she gave out 6 of these to her brother, then she finally has left with her, 33 minus 6 which equals 27.

Jan now has 27 model airplanes left
