The text tells us 215 is 86% of the questions
We are looking for 100% of the questions

We get that number by:
Multiplying 100 and 215 and dividing it by 86

\frac{100 \times 215}{86}

And that equals 250

Consider f(x)=x+7 and g(x)=x^2-1 find (g of f)(x)
finlep [7]

Answer:

g(f(x))=x^2 + 14x + 48

Step-by-step explanation:

you insert (x+7) into every x in the g(x) equation, so g(x)=(x+7)^2 - 1. then you simplify it by doing (x+7)(x+7) which gets you x^2 + 14x + 49. then you subtract the 1 from the equation to get g(f(x))=x^2 + 14x + 48.
