Explicación paso a paso:
3.- √12² + √3² - 11
12 + 3 -11 =4
4.- (x + y)² = 12 ²
(x + y)² = 144
x² + 2xy + y² =144
2(7) + x² + y² = 144
x² + y² = 144 - 14 = 130
d( ̄▽ ̄)=====b
3- S= ( √ 12)² + 2( √ 12) ( √ 3) + ( √ 3)²
S= 12 + 2 √ 36 + 3
S= 12 + 2(6)+ 3
S= 15 + 12
4- (x²+y²) = x² + 2(xy) + y²
12² = x² + 2(7) + y²
144= x² + 14 + y²
144 - 14= x² + y²
