A = 7
b = -18
c = -52
Do you know what the Quadratic formula is to solve?
Answer:
x =10
Step-by-step explanation:
Using the pythagoras theorem om one of the right triangle;
(√74)² = (x/2)²+7²
74 = (x/2)²+49
(x/2)² = 74 - 49
(x/2)² = 25
Square root both sides
√ (x/2)² = ±√25
x/2 = ±5
x = 2 * ±5
x = ±10
Hence the value of x is 10
M=-1/2 because you do y1-y2 over x1-x2 and end up with 2/-4 but simplified is -1/2
The best and most correct answer among the choices provided by your question is the second choice or letter B.
<span> CM is perpendicular to AB because the triangles are isosceles and scalene.

-2 is the answer! Remove the parentheses then move the terms. After that, collect the terms and calculate. Lastly, divide both sides.
