Tyrell is correct.. If you round it, it is 750. 5 or more up the score, 4 or less let it rest.
Answer:
None
Step-by-step explanation:
Assuming you mean sides of a right triangle, we can use the Pythagorean theorem (A^2 + B^2 = C^2)
We have A and B, so we can plug those into the equation.
(16)^2 + B^2 = (14)^2
(16)^2 is 256 and (14)^2 is 196. Plug those in.
256 + B^2 = 196
Get rid of the 256 by subtracting.
B^2 = 196 - 256
B^2 = -60
√B^2 = √-60
You can't take the square root of a negative number, so the solution is not possible. We can confirm because C cannot be bigger than A or B.
Answer:
2x + y = -5 (which is Answer 1).
Step-by-step explanation:
The possible answer choices are all versions of the standard equation of a straight line: Ax + By + C = 0. If A and B are both positive, as they are here, then the slope is negative and has the form m = -A/B. Only the first answer choice passes here: with +2x and +1y, the slope is -2. This automatically eliminates the other possibilities.
Looking at the first answer choice, we see that A must be 2 and B must be 1
so that the slope is m = -2. Writing out this equation: Ax + By + C = 0.
Replace A with 2 and B with 1: 2x + y + C = 0.
Finally, replace x with -1 and y with -3: 2(-1) + (-3) + C = 0.
Solving this for C, we get -2 - 3 + C = 0, or -5 + C = 0, or C = 5.
We end up with 2x + y = -5 (which is Answer 1).
Divide both sides of the equation by 5.2
