Find the sum. Write double you used.
4+5=

18

Step-by-step explanation:

Write double you used. is twice of what I used so

8+10=18

or

4+4+5+5=18

or 4+5=9*2=18

Hey there!

4 + 5 = 9

I am not really sure what you mean by "write double you used", but if you wanted the double of 9, it would be 18.

Hope this helps!

Have a great day!

step-by-step explanation:

(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
