a common what? denominator?
Answer:
the quadratic formula is ax^2 + bx + c", if the first one is expanded out I will be 6x^2+8x+27 so that's the answer
we have

we know that
The volume of a cube is equal to

where
b is the length side of a cube
Using a graph tool------> find the roots of the polynomial
see the attached figure
x=4
so

therefore
<u>The answer is</u>
the length side of a cube is equal to (x-4)
The sum of the measures of the angles of a triangle is 180 degrees.
An isosceles triangle has two congruent sides.
The angles opposite the congruent sides are congruent.
Just like the bottom left angle measures x, the bottom right angle also measures x.
x + x + 38 = 180
2x + 38 = 180
2x = 142
x = 71
