Answer:

x² + 6x + 9

Step-by-step explanation:

(x + 3)² = (x + 3)(x + 3)

Each term in the second factor is multiplied by each term in the first factor , that is

x(x + 3) + 3(x + 3) ← distribute parenthesis

= x² + 3x + 3x + 9 ← collect like terms

= x² + 6x + 9

Answer:

51ft, 17ft, 39ft

Step-by-step explanation:

longest = x

2nd = $\frac{1}{3}$ x

3rd = x - 12

P = 107

a + b + c = Perimeter

x + $\frac{1}{3}$ x + x - 12 = 107

$\frac{7}{3}$ x -12 = 107

$\frac{7}{3}$ x = 119

x = 51

$\frac{1}{3}$ x = 17

x - 12 = 39
