Question

Write the expanded version of each expression

x(13 + 12y - 3)

Answer 1

13x + 12yx - 3x

Answer 10x + 12yx is also right since it is just a fully simplified version of the equation above.

Explanation:

In order to get the expanded version of this expression, we would just have to get rid of the brackets by multiplying each number inside the brackets by x. And so we get...

x(13 + 12y - 3) = 13x + 12yx - 3x = 10x + 12yx

Answer 2

13x + 12xy - 3x

Explanation:

x(13 + 12y - 3)

You want to distribute the x across each term in the parentheses.

x • 13 = 13x

x • 12y = 12xy

x • -3 = -3x

Combine terms.

13x + 12xy - 3x

Hope this helps!
