Question

Find the value of x and simplify completely. Just answer needed , not explanation

Answer 1

x=(27)^2+y^2

=√729+y^2( root of 729+y^2)

= 27+√y^2

Answer 2

x=9√10

solution,

`{y}^(2) = 3 * 27 \\ {y}^(2) = 81 \\ y = √(81) \\ y = \sqrt{ {9}^(2) } \\ y = 9 \\ \\ {y}^(2) + {27}^(2) = {x}^(2) \\ or \: {9}^(2) + {27}^(2) = {x}^(2) \\ or \: 81 + 729 = {x}^(2) \\ or \: 810 = {x}^(2) \\ or \: x = √(810) \\x = 9 √(10)`

hope this helps...

Good luck on your assignment..
