if a linear equation has solutions (-3,3), (0,0)and (3,-3)then it is of the for Equation of the line parallel to x-axis and 6 units above the origin is

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
