Nicole wants to buy a pair of jeans. The original cost of the jeans is $42.50, and the markup is 10 percent. How much will she have to pay for the
jeans?

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

might be the correct answer will be question number 2

48+y= ?

the y is the variable and the ? could also be a variable
