Question

Which expression is not equivalent to

5x + 6?
A
4x + 7 + x - 1
B
3x + 3 + 2x + 3
C
5(x + 1) + 1
D
x(5 + 6)

Answer 1

Expression D is not equivalent to 5x + 6.

Step-by-step explanation:

To determine which expression is not equivalent to 5x + 6, we can simplify each expression and compare them to 5x + 6. Let's simplify each expression:

A) 4x + 7 + x - 1 simplifies to 5x + 6, so this expression is equivalent.

B) 3x + 3 + 2x + 3 simplifies to 5x + 6, so this expression is equivalent.

C) 5(x + 1) + 1 simplifies to 5x + 6, so this expression is equivalent.

D) x(5 + 6) simplifies to 11x, which is not equivalent to 5x + 6.

Therefore, expression D is not equivalent to 5x + 6.

Answer 2

5x + 6

4x + 7 + x - 1 < Lets see if this one works
4x + 1 = 5x
5x + 6 << Equal

3x + 2x = 5x
5x + 6 << Equal

5(x + 1 ) + 1
5x + 5 + 1
5x + 6 << Equal

x(5+6)
5x + 6x << Not equal

Answer: D) x(5 + 6) This one is not equal.
