Explanation:
To increase the area of the rectangular pig pen to 150m² by increasing the length and width by the same amount, we can use the following equation:
(L + x)(W + x) = 150
where L is the length of the original pig pen, W is the width of the original pig pen, and x is the amount by which both dimensions are increased.
To enter this equation into Desmos, you can use:
(L + x)(W + x) - 150 = 0
where L = 10 and W = 5.
Therefore, you can enter:
(L + x)(W + x) - 150 = 0 where L = 10 and W = 5.
I hope this helps!
