Which of these shows 7 + 2y rewritten using the commutative property of addition? 7y + 2
2y + 7
7 − 2y
2y − 7

2y + 7

Step-by-step explanation:

The commutative property BASICALLY says that something is the same backwards and forwards. In this case, 7+2y = 2y+7

2y + 7.

Hope this helps! Even though I answered this after a week. :D

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
