# Identify the expression equivalent to 2x+8 by substituting x = 7 and x = 5. a. 2x+10 + 10 b. 2(x + 2) c. (x+4) + (x+4) d. (x+4) e. 2(2x + 4)

The answer is c (x+4) + (x+4)

Step-by-step explanation:

c

Step-by-step explanation:

C is the answer because the expression pulled apart is just an addition problem between two parenthesis. I hope this helps!

Step-by-step explanation:

C.

Step-by-step explanation:

Given:

The expression is given as:

The values of 'x' are:

Now, plug in 7 and for 'x' in the above expression and determine the value of the expression.

When , the expression is:

Now, let us check the value of each of the options and check which expression is equivalent to the given expression.

Option A:

Plug in 5 for 'x' and simplify. This gives,

So, this expression is not equivalent to the given expression.

Option B:

Plug in 5 for 'x' and simplify. This gives,

So, this expression is not equivalent to the given expression.

Option C:

Plug in 5 for 'x' and simplify. This gives,

Now, plug in 7 for 'x' and simplify. This gives,

So, this expression is equivalent to the given expression.

Option D:

Plug in 5 for 'x' and simplify. This gives,

So, this expression is not equivalent to the given expression.

Option E:

Plug in 5 for 'x' and simplify. This gives,
