answer is attached in the image below
15000 because 15kg x 1000 = 15000g
Answer:
See like terms have the same variables
E.g 2x+4y-x+7y
We should take the same variable together with the same signs so here
2x-x will be 1x
4y+7y will be 11 y
So x+11y
Hope it helps!
f(-12) = -12(-12) + 100 = 144 + 100 = 244
