If 2x+5=8x, then 12x=?

mr_godi [17]

Answer:

$\boxed{10}$

Step-by-step explanation:

$2x+5=8x$

$\sf Subtract \ 8x \ from \ both \ sides.$

$2x+5-8x=8x-8x$

$-6x+5=0$

$\sf Subtract \ 5 \ from \ both \ sides.$

$-6x+5-5=0-5$

$-6x=-5$

$\sf Divide \ both \ sides \ by \ -6.$

$\displaystyle \frac{-6x}{-6} =\frac{-5}{-6}$

$\displaystyle x =\frac{5}{6}$

$\sf Evaluate \ 12x.$

$\displaystyle 12 \cdot \frac{5}{6} =\frac{60}{6} =10$

Which equation justifies why 93-3√9?

Simora [160]

Considering the conversion from exponent to radical, the equation that justifies why the expression $9^{\frac{1}{3}} = \sqrt[3]{9}$ is correct is.

$(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9$

<h3>How is the conversion from exponent to radical realized?</h3>

The conversion of rational exponents to radical notation is modeled by:

$a^{\frac{n}{m}} = \sqrt[m]{a^n}$

In this problem, the expression is:

$9^{\frac{1}{3}} = \sqrt[3]{9}$

And the equation that shows that this is correct is:

$(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9$

Sole for the blanks. (x +__ )^2 = __

KatRina [158]

Answer:

x^2 + 2ax + a^2

Step-by-step explanation:

Well, not having enough information to solve the problem, what we can do is assign a name to what adds x and work from there, once we know the value we replace it with "a" what will be the letter used for that space blank and will serve us for any value

(x + a )^2 = __

being squared it repeats and multiplies

(x + a) * (x + a)

we multiply all terms with each other

x * x + x * a + x* a + a * a

solve

x^2 + 2ax + a^2
