Answer:
x=2
Step-by-step explanation:
let the unknown number be x
now we are to find x regarding the question as an equation, let's form the equation to solve for x
the interpretation of the question is:
(x² + x)/3 = x
by collecting the like terms:
(x²+ x) = 3x
x² + x = 3x
x² = 3x - x
x² = 2x
x = 2
Answer:
upper and lower results have to be the same
so set them equal
5x = 2x + 1
subtract 2x on each side
3x = 1
devide each side by 3
x = 1/3
You are welcome
1/4 is a fraction equivalent
Answer:
x = 32
Step-by-step explanation:
This is an equilateral triangle. This means the angles of the triangle are all equal. Since the sum of a triangle's angles is 180°, that means each angle will be 60°.

Answer:
f(x)=-4x^2-6x-1
g(x)=-x^2-5x+3
(f+g)(x) = (-4x^2-6x-1) + (-x^2-5x+3)
-4x^2 - 6x - 1 -x^2 - 5x + 3
= -5x^2 - 11x + 2
