This question doesn't quite make sense as worded.
I believe what's being asked is "What is the hypotenuse of a right triangle in which the two sides abutting the right angle have lengths or 2 and 7?"
72 + 22 is just a mathematical expression. It doesn't have a hypotenuse.
The hypotenuse of a right triangle can be found using the equation
A2+B2=C2, where the side of length C is the hypotenuse.
72 + 22 = 49 + 4 = 54 = C2
So, C is the square root of 54
C = sqrt(54) = 7.34846922834... this is the approximate answer.
The exact answer is 3*sqrt(6) (because 32 is 9 and 9*6=54)
7^2 + 3^2 = 58
Negative 11
(9x + 7)(x - 2)
It depends. Is the entire expression squared or just radical 7?Assuming the latter, then 6 + (√7)^2 = 6 + 7 = 13.
They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.
This is the common form of the Pythagorean Theorem. It describes the relationship between the two legs of a right triangle and the hypotenuse.
7^2 + 3^2 = 58
1 squared plus 8 squared or 4 squared plus 7 squared
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.
To find the answer, You Find the square root of 7 Squared (7^2) and add 9 Squared (9^2). So you have Sqrt(7^2+9^2). Works out at about 11.40175
2x2 + 28xy + 98y2 = 2(x + 7)2.

7(3y-2)-(-4y+9)
I think this means (x+7)squared + (y-5)squared =4squared, which represents a circle centred at -7,+5
They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.
