Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)

Step-by-step explanation:

x^2-8x=24 <- subtract 24 from both sides

x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a

-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify

(-(-8) +/- 4sqrt(10) )/2 <- sepereate

(-(-8) +/4sqrt(10) )/2 , (-(-8) - 4sqrt(10) )/2 <- simplify

2(2+sqrt(10)) , 2(2-sqrt(10) =x

What is 21 1/4% expressed as a fraction?

Neporo4naja [7]

Answer:

$\frac{17}{80}$

Step-by-step explanation:

we have

$21\frac{1}{4}\%$

Convert mixed number to an improper fraction

$21\frac{1}{4}=21+\frac{1}{4}=\frac{21*4+1}{4}=\frac{85}{4}$

$21\frac{1}{4}\%=\frac{85}{4}\%$

Convert percent number as a fraction

$\frac{85}{4}\%=\frac{85}{4}:100=\frac{85}{4*100}=\frac{85}{400}$

Simplify

Divide by 5 both numerator and denominator

$\frac{17}{80}$

I'll make you brainlist and 40 points (2z²)^-3 please hurry

gladu [14]

Is the goal to simplify? You just need to multiply the exponents for each factor:

(2z^2)^(-3)
= 2^(-3) x z^(2 x -3)
= (1/2)^3 x z^(-6)
= (1/8) x (1/z)^6
= 1/(8z^6)
