8*10 squared as a decimal would be 2.8
slope of a line that is perpendicular to the line y=-3x is 1/3
What is slope of line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. where "m" represents a line's slope. So, the slope of a line is tanθ.
y=-3x
tanθ=slope = y/x= -3
Slope(M) of this equation is -3
Let the slope of its perpendicular line is m
As we know that the product of the slopes of perpendicular lines is -1
so,
M*m =-1
-3 * m= -1
m=1/3

6y=-4x+30
y= -2/3x +5
hope this helps!
Here, this should work, sorry if i'm incorrect

B Is base Length
A is the side face
Sorry if im confusing, you can also go use google</span>
1/4 + 1/6 = 10/24 reduced (simplest form) = 5/12
