9+b2=11
b2=11-9=2
b=positive or negative sqrt(2)
X = √63
92 is the same as 9 * 9 which equals 81. 112 is the same as 11 * 11 which equals 121.
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.
11 times 3 squared is equal to 11 times 9, which equals 99.
x^2 +9 =x^2 -9 9=-9 No solution
the answer is 11cm. 3 squared is 9 9+2=11
7(3y-2)-(-4y+9)
11 + 7 + 9 = 27
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
2^2 + 3^2 = 4 + 9 = 13
6 squared plus 9 squared is equal to 117.
2 squared plus 2 squared equals 16 because 2 squared is 4 times 4 equals 16. Math: 4x4=16 so your answer is 16 :)!
