Given (x ＋ X & # 178; + 1) (Y ＋ Y & # 178; + 4) = 9, find the value of X √ Y & # 178; + 4 + y √ X & # 178; + 1

Given (x ＋ X & # 178; + 1) (Y ＋ Y & # 178; + 4) = 9, find the value of X √ Y & # 178; + 4 + y √ X & # 178; + 1

77/18
I don't know if it's done with rotation symmetry
Let y = 2T, t and X rotate symmetrically, and then we can get the solution

Given X-9 + (y + 3) &# 178; = 0, find the value of X + 3Y

｜x-9｜+(y+3)²=0,
∵｜x-9｜≥0,(y+3)²≥0,
∴｜x-9｜=0,(y+3)²=0,
∴x=9,y=-3
∴x+3y=9-9=0
Mingjiao answers for you,
Please click [satisfied answer]; if you are not satisfied, please point out, I will correct it!
Hope to give you a correct reply!
I wish you academic progress!

2 (x-3) & 178; - 1 = 49 find x

2（x-3）2＝50
（x-3）2＝25
x-3＝±5
X = 8 or x = - 2
