(-5)(-5)(-5)=-125

Given the expression:

\displaystyle \large{ \sqrt[3]{ - 125} }

Definition:

\displaystyle \large{ y  = \begin{cases}   \pm \sqrt[n]{x}  \longrightarrow n  = (2,4,6,8,...)  \:  \: (x \geqslant 0) \\   \sqrt[n]{x}\longrightarrow n = (1,3,5,7,...) \:  \: (x \in \R) \end{cases}}

First, factor the -125. -125 comes from (-5)×(-5)×(-5) or (-5)^3.

\displaystyle \large{ \sqrt[3]{ ( - 5) \times ( - 5) \times ( - 5)} }

Because if (-5)^2 = 25 then 25×(-5) again will be -125.

Since this is the cube root, we have to pull out 3 terms in one. There are 3 fives that we can take off and therefore,

\displaystyle \large \boxed{ - 5}

Shera is building a cabinet she is making wooden braces for the corners of the cabinet. What is the surface area
MA_775_DIABLO [31]
The correct answer for the question that is being presented above is this one: "28 in^2." 

We have to get the individual area of each surface.
A1 = 1*3*2 = 6
A2 = 1*3*2 = 6
A3 = 1*2*2 = 4
A4 = 2*3*2 = 12
Area = A1 + A2 + A3 + A4 
Area = 6 + 6 + 4 + 12
Area = 28 in^2

Which equation is written in slope-intercept form?
zhuklara [117]

Answer:

<h2>A. y = 3x - 2</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

<em>y = mx + b</em>

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have

<em>A. y = 3x - 2   - it's the slope-intercept form</em>

<em>B. x = 1/2y + 8   </em><em>NOT</em>

<em>C. 2x + 5y = 12 </em><em>NOT</em><em> - it's the standard form</em>

<em>D. 3y = 8x - 5  </em><em>NOT</em>
