Answer: If you need to find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem if you know the length of the other two sides. Square the length of the 2 sides, called a and b, then add them together. Take the square root of the result to get the hypotenuse
So when you opened up the parenthesis on the right side of the question, you added -2 to 5 instead of multiplying. Since there is no addition sign in between -2 and the parenthesis, it should be multiplication, so -2x + -10.
So now the answer would be 10 = -10.
Which leads me to believe that this question wasn't written correctly because 10 does not equal -10 for sure.
3/z, 3 divided by z! Its easy, what does quotient mean?
First calculate the Area of MOP by using congruent altitudes.
(Area MOP)/(Area AOM) = PO/OA = (Area BOP)/(Area AOB)
Area MOP = (Area AOM)*(Area BOP)/(Area AOB) = (45)*(15/75) = 9.
Now, let Area CMP = x. And use two sets of triangles with congruent altitudes.
(Area CMP)/(Area BMP) = x/(9+15) = x/24 = (CP)/(BP).
(Area CAP)/(Area BAP) = (x+54)/90 = (CP)/(BP)
So,
(Area CMP)/(Area BMP) = (Area CAP)/(Area BAP)
or
x/24 = (x+54)/90
90x = 24 (x+54) = 24x + 1296
66x = 1296
x = 19 
The endpoint T is located at C. (3, 7)
