Question #5936e

Answer 1

After solving, you will be left with 2`x` + 14.

Explanation:

Using the commutative property, move the 2 to the other side of the parenthesis. Like this:
2(`x` + 7)
Next, use the distributive property and multiply the 2 times `x`, then multiply 2 times 7. It should look like this after multiplying:
2`x` + 14
After all of this, you cannot simplify it any more.
The answer is 2`x` + 14.

Answer 2

`= x^2 +14x+49`

Explanation:

If the question was intended to be `(x+7)^2`, then we have:

`(x+7)(x+7)" "`multiply by multiplying each term in the first bracket by each term in the second bracket:

`= x^2 +7x +7x+49`

`= x^2 +14x+49`

NOte that this is in the form:

`(a-b)^2 = a^2 -2ab +b^2`
