If sarah was going to the mall with her three friends. sarah friends spent 50 dollars each and sarah spent twice as more as her , how much money do they have all together?

They would have $250 all together

First you would calculate Sarah's number of friends times $50:

3 * 50 = 150

Then you multiply Sarah's amount by 2, or 50 x 2, which would be 100.

Lastly you add 150 and 100 =

$250

(If Sarah doubled all of her friends, the answer would be 300)

the answer will be

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
