Answer:

Option C is correct

600 in^2

Step-by-step explanation:

Surface area of cube(S) is given by:

S = 6a^2            ....[1]

where, a is the side length of a cube.

As per the statement:

A cube with side length 9.9 in.

⇒a = 9.9 in.

Substitute in [1] we have;

S = 6 \cdot (9.9)^2 = 6 \cdot 98.01 = 588.01 \approx 600 in^2

Therefore, the estimate the surface area of a cube is, 600 in^2

Please write an equation for line N.
Lana71 [14]

Answer:

y = x-1

Step-by-step explanation:

First step is to find the slope

Take two points on the line  (1,0) and (2,1)

m = (y2-y1)/(x2-x1)

   = (1-0)/(2-1)

   = 1/1

The slope is 1

The y intercept ( where it crosses the y axis is -1)

The slope intercept form of the line is

y = mx+b where m is the slope and b is the y intercept

y = 1x-1

y = x-1
