Click and drag like terms onto each other to simplify fully. 1+x^2-3+2y+7x^2+3+3y
Rashid [163]

Answer:

8x^2 + 5y + 1

Step-by-step explanation:

1 + x^2 - 3 + 2y + 7x^2 + 3 + 3y

group like terms

= x^2 + 7x^2 + 2y + 3y + 1 - 3 + 3

add similar items

= 8x^2 + 2y + 3y + 1 - 3 + 3

add similar items

= 8x^2 + 5y + 1 - 3 + 3

= 8x^2 + 5y + 1

Use the Distributive Property to solve the equation. 2x−4​(x−3​)=−8+5x-8
andrew11 [14]

Answer:

x = 4

Step-by-step explanation:

Distributive Property: a(b + c) = (a*b) + (a*c)

           2x - 4(x - 3) = -8 + 5x - 8

2x + x * (-4) - 3*(-4) = -8 + 5x - 8

          2x - 4x + 12  = -8 + 5x - 8    

   2x -  4x - 5x + 12 = -8 - 8

               -7x  + 12  = -16

                       -7x  = -16  -12

                      -7x   = -28

                          x = -28/-7

x = 4
