I’m so confused on how it get the answers

So, you just fill in so for number 1 you will take f(x) = x^2, and every where there is an x, you replace with a -5 so it would be f(-5) = -5^2 which is 25. Same with the others like number 2, take g(x) = x+5 and replace x  with -12, g(-12)= -12+5, which would be -7.

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
