Answer:
30
Step-by-step explanation:
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.

To find a perfect square we want the equation to look like (y - 8)(y-8) because
the two numbers that add up to -16 and multiply into 64. are -8, -8. -8^2 is 64.

Hello there!
To solve a function by graphing would be to graph it and then look at where it intersects the x-axis. This way is not always accurate due to the fact that one cannot graph it to the exact point all the time, and even if they can or use a graphing calculator, it's difficult to read the graphs too. For those two reasons, solving by graphing throws off the answer most of the time, therefore this method is rarely reliable and it's important to learn other ways to solve.
I really hope this helps!
Best wishes :)
