Answer:
the correct choice is marked
Step-by-step explanation:
Let x represent the smaller number. Then the larger number is 8x, and the difference is ...
8x -x = 280
7x = 280 . . . . . simplify
x = 40 . . . . . . divide by 7
The larger number is 8x = 8(40) = 320.

Answer:
5
Step-by-step explanation:

f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
f(-2) = 5
