Answer:
10x^2 -18
Step-by-step explanations
since f(x) is becoming the new x then youd subtitute the equation into the x of the g(x) equation. which would be 5(2x^2 -5) +7 which is 10x^2 -25 +7.and you'd simplify from there.
10 * 10^2 - 7.79* 10^3
they have to be to the same power to add or subtract
change 10*10^2 to proper scientific notation (only 1 number before the decimal) 1*10^3
1*10^3 - 7.79*10^3 = (1-7.79) * 10^3=-6.79*10^3

Remember that
A statistical question is a question that can be answered by collecting data that vary.
so
Classify
Hw tall are the memmbers of my class? -------> Is a statistical question
How tall am i? --------> is a nonstatistical question
How old are the students in my school? -------> Is a statistical question
A statistical question can be measured and controlled, while a nonstatistical question cannot provide for the measurement.
