X^3*x^4=x^12 whats the answerrr

erica [24]

Answer:

I hope it helps it was the best I can do.

Step-by-step explanation:

-x12 + x7 = 0

Factorization:

−x7(x − 1)(x4 + x3 + x2 + x + 1) = 0

Solutions based on Jenkins–Traub algorithm:

x1 = … = x7 = 0

x8 = 1

x9 = −0.809017 − 0.587785i

x10 = −0.809017 + 0.587785i

x11 = 0.309017 − 0.951057i

x12 = 0.309017 + 0.951057i

What is the measure of angle C? A 28° B 62° C 90° D. 10°

Ray Of Light [21]

For this case we have that by definition, the sum of the internal angles of a triangle is 180 degrees. So, we have:

$(5x + 12) + (6x + 30) + (2x + 8) = 180\\5x + 12 + 6x + 30 + 2x + 8 = 180$

We add similar terms:

$13x + 50 = 180\\13x = 180-50\\13x = 130\\x = \frac {130} {13}\\x = 10$

Answer:

$x = 10$
