Question

The rectangle below has an area of 2 + 11x + 28 square meters and a length of x + 7 meters.

What expression represents the width of the rectangle?
1 +7
Width
22 +11+28
​

Answer 1

x+4

Explanation:

We can first note that the constants must multiply to 28. So its ?x+4

Now we have to figure out what that question mark is.

When we look at the first term, we can see that there is nothing there.

That means that the ? is just 1.

We end up with : x+4
