2 squared plus 2 squared equals 16 because 2 squared is 4 times 4 equals 16. Math: 4x4=16 so your answer is 16 :)!

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.

The Pythagoream Thereom is a^2 + b^2 = c^2. Written out it is a squared plus b squared equals c squared.

b = sqrt32 or 4 root 2

(2, -2)

If I have this correct you are asking x^2 + 10^2 = 12^2 Then x=6.633249507108

equals 2 p squared

a number equals 2

7(3y-2)-(-4y+9)

They intersect at the point of: (-3/2, 11/4)

They are +/- 5*sqrt(2)

x = the square root of -2

The center of the circle given by the equation (x - 3)2 plus (y + 2)2 = 9 is (3,-2).

No because no 2 numbers can be squared to equal 4. 1 squared is 1 2 squared is 4 so the lowest answer is 5.

The missing number is 49. This is why: 1 plus 2 equals 3, then 3 squared is 9. 2 plus 3 equals 5, then 5 squared is 25. Therefore, the missing number must be 49 to make the number sentence (3 plus 4 equals 7, then 7 squared is 49) true.

Using the discriminant of b^2 -4ac = 0 the value of k works out as -2

Negative 11

Simple equation lad. In your example, you said n=4 and x= n squared + n - 1 + (n-2)squared + (n-3)squared. You simply write n²+n-1+(n-2)²+(n-3)² I hope that is what you mean by what you say. P.S. To get the to the power of sign, hold alt and press 0178 for ², and 0179 for ³

x = Â±2

yes 1 + cot x^2 = csc x^2

equals x+2 PROVIDED x is not -2. If x is -2, the ratio is not defined.
