It is the equation of a circle with radius of 6
and its center at the origin.
x + 36 = 82x = 82 - 36x = 46
Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.
16 + x = 36x = 36 - 16 = 2016 + 20 = 36
36 x 50 yards equates to 16,200 square feet.
x = plus or minus 6.
x = -13
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
x^2 + 12x = 5 x^2 + 12x + __ = 5 + __ x^2 + 12x + 36 = 5 + 36 (The 36 I got from taking half of 12 and then squaring that number (which is 6).) (x + 6)^2 = 41 x + 6 = (the square root of 41) x = (the square root of 41) - 6. Hope that helped :)
x=16
x=26
x2 + 13x + 36 = 0 so (x+4)(x+9) = 0 so that x = -4 or x = -9
x = 7
