Answer:
Use Pythagorean Theorem which is a squared (one of the numbers thats side is with the 90° angle) plus b squared (the other number thats side is next to the 90° angle) equals c squared (the hypotenuse).

122
Step-by-step explanation:
366 divided by 3
Answer:
(2) Real and equal (i.e., repeated roots), if D = 0.
Step-by-step explanation:
.In a quadratic equation ax2 + bx + c = 0, if discriminant is D= b2 - 4ac, then roots of the quadratic equation are
Real and equal (i.e., repeated roots), if D = 0.
If the D > b² - 4ac then it's real and distinct.
To answer, substitute the value of y in the second equation to that of the first.
x² + (x + 2)² = 100
Simplification leads to,
x² + x² + 4x + 4 = 100
2x² + 4x + 4 = 100
x² + 2x - 48 = 0
The roots of this equation are x = 6 and x = -8. Thus, the answer is letter C.
Answer - 720
You would do 6 x 5 = 30 to get how many dawn had
Then you’d do 30 x 4 = 120 to get how many Charlie had
Then you’d do 120 x 3 = 360 to get how many Ben had
Then 360 x 2 = 720 to get the original amount
Have a good day :)
