Odd, even or neither:
if 
f(-x) = f(x) => even 
f(-x) = -f(x) => odd

f(-x)=f(x)=even
f(-x)=-f(x)=odd

If one root is the square of the other in the equation 8+mx+27x²=0,find the value of m

aleksklad [387]

Answer:

The value of $m$ is -30.

Step-by-step explanation:

Let $27\cdot x^{2}+m\cdot x +8 = 0$ , we notice that expression is a second order polynomials. We can rearrange the polynomial and use factorization to calculate all roots:

$x^{2}+\frac{m}{27}\cdot x + \frac{8}{27} = 0$ (1)

$-x^{2}-x = \frac{m}{27}$ (2)

$x^{3} = \frac{8}{27}$ (3)

From (3) we find the least root:

$x = \sqrt [3]{\frac{8}{27}}$

$x = \frac{2}{3}$

By (2) we have the value of $m$ :

$m = -27\cdot (x^{2}+x)$

$m = -30$

i have 60+8x=108 x=6 but for the other equation i dont know how to get rid of the 3x to solve for the y.

LUCKY_DIMON [66]

Angle a is congurent to angle e, so 60+8x=108
same with c and g.
so 8y-3x=62
just plug in x for there (6)
so 8y-24=62
then 8y=88
y=11
