sqrt(169-20c)
8 and 6
8*6 = 48

prependicular means that x * 1/x = -1 so,
the slope of the line is -2
y=-2x+b
now plug in the coordinates
-4 = -2*(3) + b
solve for b:
-4 = -6 +b
b = 2
the line is: y=-2x+2
206.2648 cm^2 total

could you clearly tell me what you want.
(-sqrt(3),sqrt(3))
changed it sry
Why don't you upload a photo that might help.

Use foil:
x(2x^2-5x-7) * -2(2x^2-5x-7)
2x^3-5x^2-7x-4x^2+10x+14
2x^3-9x^2+3x+14
