4x^ + 2xy + 2xy + y^ - x^ + 2xy + 2xy - 4y^

3x^ - 3y^ + 8xy , I believe ! I'm not 100% on this one though, sorry,!!

Please help❤️❤️ It’s for 20 pts!!
solong [7]
If you need part A, draw a person and label them 6 feet tall and a shadow coming off of him that is five feet long and draw a basketball hoop that and label it X feet tall and draw a shadow coming from it that is 8 feet long. To solve, you use proportions 6/5=X/8 solving this you get X=9.6 feet which is the height of the rim. Therefore, the rim does not meet regulation height, since the required height (10 feet) is greater than the actual height (9.6 feet).

What is the length of the hypotenuse of the triangle when x=14
astra-53 [7]

The length of the hypotenuse will be equal to H=122.25 when value of x=14.

<h3>What is pythagorean theorem?</h3>

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal the square of the sum of the other two sides.

It is given that:

Value of x=14

The perpendicular is  =6x+5=6x14+5=89

The base is  =6x=84

So by using the Pythagorean theorem:-

H^2=P^2+B^2\\\\\\H^2=89^2+84^2\\\\\\H=\sqrt{89^2+84^2}\\\\\

Hence the value of hypotenuse will be H=122.25

To know more about the Pythagorean theorem follow
