Tell wether or not each of the following situations illustrated are quadratic equations. Answer each by a mathematical sentence.

1. The length of a swimming pool is 8m longer than its width and the area is 105m.

2. Edna paid atleast Php. 1,200 for a pair of pants and a blouse. The cost of the pair of pants is Php. 600.00 more than a cost of the blouse.

Thankyou po Ate. Teka, pano po naging Quadratic yung number 1? Diba may squared dapat?
If esi.simplify mo yan magiging 8w+wsquared =105m. diba?
Ahhhh. Sige po. Hindi po talaga ako magaling sa Math T.T
Thank you
