The equations presented in the choices above are all derived from the Pythagorean theorem. This states that the sum of the squares of the two shorter sides is equal to the square of the longest side which is also referred to as the hypotenuse.
If the sum of the squares of the shorter sides is smaller compared to the square of the hypotenuse then, the triangle is OBTUSE. The answer therefore to this item is letter A.
Sub x^2+12x+10 for y in other equaiton
-8x+x^2+12x+10=10
x^2+4x+10=10
minus 10 both sides
x^2+4x=0
factor
(x+4)(x)=0
set to zer
x+4=0
x=-4
x=0
x=-4 or 0
sub back
y=0^2+12(0)+10, y=10
(0,10)
y=(-4)^2+12(-4)+10, y=-22
(-4,-22)
solutions are
(0,10) and (-4,-22)

Answer:
x=4
Step-by-step explanation:
x/3-1/2=5/6
Add 1/2 to each side
x/3-1/2+1/2=5/6+1/2
x/3 = 5/6+1/2
Get a common denominator on the right
x/3 = 5/6+3/6
x/3 = 8/6
x/3 = 4/3
Multiply each side by 3
x/3 *3 = 4/3*3
x = 4
