Answer:
No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.
Step-by-step explanation:
Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).
- we can use 7 and 10 interchangeably.
Fill in the equation, 
where c = 12, and a or b = 7 or 10.
To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.
Therefore, 
or 
==> 49 + b^2 = 144 ==> <u>b= </u>
<u> ==> </u><u>9.746</u>
b= 9.7, not 10.
==> 100 + b^2 = 144 ==> <u>b = </u>
<u> ==> </u><u>6.633 </u>
b= 6.6, not 7.
Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.
Hope this helps!

Answer:
d 4x +y = 17
Step-by-step explanation:
The only equation satisfied by the given point is also in standard form:
4x +y = 17
__
Trying the given point in the different equations, we have ...
a) 4x -y = 4(5) -(-3) = 23
b) 4x +y = 4(5) +(-3) = 17
c) -4x +y = -4(5) +(-3) = -23
d) 4x +y = 4(5) +(-3) = 17 . . . . equation D matches the point
Solving for y, we have ...
y = -4x +17 . . . . a slope of -4 . . . . equation D matches the slope
