Answer:
x = 40
Step-by-step explanation:
Answer:
height is 15
Y = L = Length
therefore 15y = (-x^2) +(300/20)
Step-by-step explanation:
15 = -x^2 +(300/20)
is the same as;
15 = (300/20) - (x^2)
we just add y to 15 and that can represent a division for x
y = L
Where area cm^2 can be shown as 300 as 15 x 20 = 300
when we divide by length we get the height as asked in the question.
Answer:
The 4 interior angles in the square are each 90 degrees. The four angles formed by the intersection of the 2 diagonal lines are each 90 degrees. The rest of the angles <PQT, <RQT, etc. Are all 45 degrees.
The answer is 4 x^2y. <em> I cannot explain to you how I know I'm right. I'm the type of person who HAS to do the work in their head . I am a very experienced person in any Mathematics area. I am NOT saying I'm an expert , but it is one of my strongest subjects . </em>
