I signed up for plus and my son is trying to use it and its says he needs to get the plus? Could someone please clarify?

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2

next time, share the answer choices.   .
