I would recommend combing like terms (ex- 10x-9x=x) so it could be 15x^2+x-6 . I recommend using something like mathpapa to show you step-by-step how to do it, and if you know, then it just gives you a quick answer
Answer: x=17
Step-by-step explanation:(6x+x+4x)+(10+17-34)=180
we know this because triangles always equal 180o so the 3 angles equa; 180 so 187/11 + 17
For the general quadratic equation ax^2 + bx + c = 0 the discriminant is b^2 - 4ac.
So, for x^2 + x + 2 = 0, a = 1, b = 1, and c = 2, therefore
b^2 - 4ac = 1^2 - 4(1)(2) = 1 - 8 = - 7.
Answer: - 7
Answer:
x = 50, y = 25
Step-by-step explanation:
This is a 30° 60° 90° triangle. In this triangle, the long leg of the triangle will be the short leg length multiplied by √3, so we can simply divide by √3 to find the short leg (y).
y = 25√3/√3 = 25
Therefore, y = 25.
Lastly, in this type of triangle, the hypotenuse is double the short leg length.
x = 2(25) = 50
Therefore, x = 50.
