Answer:
f(1) = 10
Step-by-step explanation:
Here you can just replace any x with 1.
f(1) = 9(1) - (1)2 + 3(1)
Answer:
D.
Step-by-step explanation:
4 x (26 + 72) is 4 time more than the expression of 26 + 72
The angles should be included between the equal sides
Is not because 9 - 5 = 4; 15 - 9 = 6; 4 is not equal with 6!
