6) A cube has a volume of 125 mm3, what is its surface area?<br> Volume = s3<br> Area = 6x s2

Elena L [17]

<h3>~Geometry</h3>

Step-by-step explanation:

r³ = 125

r = 5 mm

...

V = 5³

V = 125 mm³

...

A = 6 . s²

A = 6 . 5²

A = 6 . 25

A = 150 mm²

The equation of the line in the graph is y = (blank) x+ (blank)

Bezzdna [24]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: y=-x-1$

____________________________________

$\large \tt Solution \: :$

Taking two points : (-1 , 0) and (0 , -1)

$\textsf{Calculate slope (m)}$

$\qquad \tt \rightarrow \: m = \cfrac{rise}{run}$

$\qquad \tt \rightarrow \: m = \cfrac{y_2 - y_1}{x_2 - x_1}$

$\qquad \tt \rightarrow \: m = \cfrac{0 - ( - 1)}{ - 1 - 0}$

$\qquad \tt \rightarrow \: m = \cfrac{0 + 1}{ - 1}$

$\qquad \tt \rightarrow \: m = - 1$

$\textsf{Y - intercept (c) of graph = -1 }$

Equation of line in slope - intercept form :

$\qquad \tt \rightarrow \: y = mx + c$

$\qquad \tt \rightarrow \: y = - x - 1$
