Answer:
x = 6 or x = -5
Step-by-step explanation:
x^2 - 30 = x
x^2 - x - 30 = 0
(x - 6)(x + 5) = 0
x - 6 = 0 or x + 5 = 0
x = 6 or x = -5
Midpoint formula is ( (x₁+x₂) / 2, (y₁+y₂) / 2 )
So that would be ( (9-1) / 2, (8-2) / 2 ) = ( 8 / 2, 6 / 2 ) = (4, 3)
Final answer: (4, 3)
The Acute Angles Of An Isosceles Triangle Never Add Up To 90°.
Answer:
x = 40
Step-by-step explanation:
The three angles in a triangle add to 180 degrees
x + 30 + (3x-10) = 180
Combine like terms
4x +20 = 180
Subtract 20 from each side
4x+20-20 = 180-20
4x= 160
Divide each side by 4
4x/4 =160/4
x = 40
The answer is 0.583, and the 3 has a bar notation
Hope this helped
btw i also do k12
