Let's solve it!
So, let's study each factor.
x + 7 = 0 -> x = -7
x² - 49 = 0 -> x² = 49 - > x = ± √49 -> x = <span>± 7
Final answer: x = 7 and x = -7

Considering the area of the rectangle, we have that the length is of 8 units and the width is of 10 units.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given as follows:
A = lw.
In this problem, the area is of 80 square units, while the length and the width are consecutive even integers, hence:
Then:
l(l + 2) = 80
l² + 2l - 80 = 0
(l + 10)(l - 8) = 0.
We need the positive measure, hence:
l - 8= 0 -> l = 8 units.
w = l + 2 = 10 units.

For the first choice x<2. This is seen by the open circle.
For the second, x ≤ -4.25. This is seen by the closed circle
For the third, the answer would be the first option.
Length = area / width
= 264 / 11
= 24 yards
