You may have the hypotenuse of a right triangle and the length of one side, and you're stuck finding the length of the other side. If you have 182 equals 62 plus b2, here's how to find the answer: 182 = 62 + b2 324 = 36 + b2 324 - 36 = b2 288 = b2 b = square root of 288 = about 16.97 Note that the square root of 288 is plus or minus 16.97, but when we're solving for the length of the side of a triangle, it can't have negative length, so we toss out the negative root and go with the positive one.
This is the common form of the Pythagorean Theorem. It describes the relationship between the two legs of a right triangle and the hypotenuse.
12 squared plus 18 squared is equal to 468.
U can subtract 18 from each side of the equation.
b + 7 = 18 subtract 7 from each side b + 7 - 7 = 18 - 7 b = 11 ----------------check in original equation 11 + 7 = 18 18 = 18 --------------checks
If that's -18y2, the answer is (3x - 2y)(x + 9y)

b= 10
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
This is the common form of the Pythagorean Theorem. It describes the relationship between the two legs of a right triangle and the hypotenuse.
12 squared plus 18 squared is equal to 468.
U can subtract 18 from each side of the equation.
25-7=18 18/3=6
(x, y) = (-3, -3) or (3, 3)
-86
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
y + y + 2 = 182y + 2 = 182y = 16y = 8whew !
