Answer: u=x^6

Explanation:

A quadratic equation is an equation written in the form

au^2 + bu + c=0 (1)

where a,b,c are coefficients and where u is the variable.

Our original equation is:

4x^{12} - 5x^6 -14=0

If we make the substitution u=x^6, we obtain

4u^2 -5u-14 =0

Which corresponds to eq.(1), with coefficients a=4, b=-5, c=-14.

How many triangles can be made with a 70 degree angle a 30 degree angle and an 80 degree angle​
uranmaximum [27]

Answer:

There are infinite number of triangles that could be achieved with those angles.

To picture this, we only have to imagine a triangle that is either smaller or bigger than the one at hand.

Tracing a series of paralell lines (which guarantee that the angles are being kept),  we can draw triangles for infinite values of x,y and z.
