92 = 81
122 = 144
81 + b2 = 144
(take 81 from both sides)
b2 = 63
b = 7.937253933

IF 2 plus 3 equals 10. 7 plus 2 equals 63. 6 plus 5 equals 66. 8 plus 4 equals 96 therefore 9 plus 7 equals?
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
Where is the center of the circle given by the equation x - 3 squared plus y plus 2 squared equals 9?
The center of the circle given by the equation (x - 3)2 plus (y + 2)2 = 9 is (3,-2).
How do you find the missing length of a triangle using Pythagoras?
The length of side A squared plus the length of side B sqaured equals the missing side of the triangle squared. So i.e. if side A is 4 and side B is 3 then 4x4 which is 16 plus 3x3 which is 9 equals 25 and the square root of 25 equals 5. So in conclusion the missing side equals 5.

x^2 +9 =x^2 -9 9=-9 No solution
What is the value of k when 4x squared plus kx plus 9 equals 0?
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
Simplify the algebraic expression 7x squared minus 4y plus 3x squared plus 5y plus 2 and evaluate it for x equals 3 and y equals 9?
7(3y-2)-(-4y+9)
Does 7 9 and 12 make a right triangle?
No, it is not. For a right triangle, from the Pythagoraen theorem, 7 squared plus 9 squared does not equal 12 squared
Is -2x squared plus 2x plus 1 equals 9 a quadratic equation?
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
9 plus 6 plus 12 equals?
27
