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)
What is 6 squared plus 9 squared?
6 squared plus 9 squared is equal to 117.
What is the solution set for -5x plus x plus 9 equals -4x plus 12?
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
What is the solution set for the equation x squared minus 6x plus 9 equals 16?
{-1,7}
What are the possible values of k when the equation x squared plus 2kx plus 81 equals 0 has equal roots?
Using the discriminant the possible values of k are -9 or 9
What is 12 plus 9 equals?
12 plus 9 equals 21.
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.
9 squared plus b squared equals 12 squared?
92 = 81122 = 14481 + b2 = 144(take 81 from both sides)b2 = 63b = 7.937253933
X squared plus 9 equals x squared minus 9?
x^2 +9 =x^2 -9 9=-9 No solution
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
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)
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.
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.
What is 6 squared plus 9 squared?
6 squared plus 9 squared is equal to 117.
9 plus 6 plus 12 equals?
27
What is 12 plus 16 plus 18 plus 20 plus 9 equals?
12 + 16 + 18 + 20 + 9 = 75
What is 2 squared plus 400?
