Find all the zeros of the equation

lapo4ka [179]

Divide both sides by -3, and replace $x^2$ with $y$ . Then

$-3x^4+27x^2+1200=0\iff y^2-9y-400=0$

Factorize the quadratic in $y$ to get

$y^2-9y-400=(y+16)(y-25)=0\implies y=-16,y=25$

which in turn means

$x^2=-16,x^2=25$

But $x^2\ge0$ for all real $x$ , so we can ignore the first solution. This leaves us with

$x^2=25\implies x=\pm\sqrt{25}=\pm5$

If we allow for any complex solution, then we can continue with the solution we ignored:

$x^2=-16\implies x=\pm\sqrt{-16}=\pm i\sqrt{16}=\pm4i$

Please help me I need help with my test review I can’t figure out m<1 and m<2

aksik [14]

Answer:

m1=12 and m2=168

Step-by-step explanation:

$m1 + m2 = 180 \: (straight \: angle) \\ then \\ x - 12 + 7x = 180 \\ 8x - 12 = 180 \\ 8x = 180 + 12 = 192 \\ x = 192\div 8 \\ x = 24\\ hence \\ m1 = 24 - 12 = 12 \\ m2 = 7 \times 24 = 168.$

(20 POINTS AND BRAINLIEST FOR BEST)

Alexxx [7]

Subtract the original from the new to find the difference:

148 - 74 = 74

Now divide the new by the difference:

148 / 74 = 2

Multiply that by 100 to get the percentage:

2 x 100 = 200%

It was a 200% increase.
