Answer:
It doesn't form a right triangle
Step-by-step explanation:
According to the Pythagorean theorem, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
a^2 + b^2 = c^2 by substituting the three values, 10, 15, and 20 you should get an equivalent value of the hypotenuse.
10^2 + 15^2 = 20^2
100 + 225 = 400
325 =/= 400
This is false.
Since this is not equivalent, it is NOT a right triangle.
Hope this helped :)
Answer:
(3,2) Choice C
Step-by-step explanation:
x-2y = -1
2x+3y =12
multiply the first equation by -2
-2x +4y = 2
add the 2 equations together
2x+3y =12
-2x +4y = 2
-----------------
7y =14
divide by 7
y =2
x-2y = -1
x -2(2) = -1
x-4 = -1
add 4 to each side
x = 3
