Answer:
9m
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2 where s is the side length
We know the surface area is 486 and the side length is z
486 = 6z^2
Divide each side by 6
486/6 = 6z^2/6
81 = z^2
Take the square root of each side
sqrt(81) = sqrt(z^2)
9 = z
Each side has a length of 9m
Answer:
in the equation y=mx+b. The equation of the line that has a slope of 0 and a y-intercept of -8 is: y=-8.
Step-by-step explanation:
If the slope of a line is undefined, then the line is a vertical line, so it cannot be written in slope-intercept form, but it can be written in the form: x=a , where a is a constant. If the line has an undefined slope and passes through the point (2,3) , then the equation of the line is x=2 .
Answer: B=36
Step-by-step explanation:
Answer
the slope intercept is y= -5/2x-6
hope this helps and have a wonderful day :)
