You subtract 2x from both sides to get why by itself. So in the end it would equal: y<-2x+7. Is that what you are meaning?
I don't know how many boys are in the classroom?
Answer:
33
Step-by-step explanation:
(3×3 )+(1/2 ×3×4) ×4 = 33
" the product " means multiply
(2ab + b)(a^2 - b^2) = 2a^3b - 2ab^3 + a^2b - b^3
when multiplied : (2a + b)(2a^3b - 2ab^3 + a^2b - b^3) =
4a^4b - 4a^2b^3 + 2a^3b - 2ab^3 + 2a^3b^2 - 2ab^4 + a^2b^2 - b^4
...result is a polynomial with 8 terms
