Answer:
The answer to number 9 is d
Step-by-step explanation:
The Amplitude is pi and the period also is the right number if you use teh mathematical formula. 2pi ÷ pi^2 is 2÷pi, so it basically has to be d, since a and b don't have the correct Amplitude and c doesn't have the correct period.
The product of 16 and 26 would be 16 * 26
This is because "the product of" means multiplication so *. Making it 16 * 26.
-4 (-x + 2) = 2 (3x - 7)
2x-4=3x-7
x=3
That would be 1
To get 13 out of 14 you must add 1.
