Which of the following expressions are equivalent to the expression 4x + 8?

choose all the expressions that are equivalent.

6x+8−2x

4(x+2)

4x+2

2(2x+8)

4(x+8)

3x+9+x−1

2(2x+4)

6x+8−2x  

4(x+2)  

3x+9+x−1  

2(2x+4)

Step-by-step explanation:

For an expression to be equivalent it must simplify to 4x + 8.

6x+8−2x   = 4x + 8 YES

4(x+2)  = 4x + 8 YES

4x+2  = 4x + 2 NO

2(2x+8)  = 4x + 16 NO

4(x+8)  = 4x + 32 NO

3x+9+x−1  = 4x + 8 YES

2(2x+4)  = 4x + 8 YES

it works trust me

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
