Answer:

32

Step-by-step explanation:

Note that

(a + b)² = a² + 2ab + b²

           = a² + b² + 2ab ← substitute given values for a² + b² and ab

          = 16 + (2 × 8)

          = 16 + 16

          = 32

$14 for a haircut plus a 15% tip anyone ???
Vlad [161]

Answer:

$16.10

Step-by-step explanation:

Simply take the original cost and multiply it by the percentage to get the tip amount then add it all together.

14 × 15% = 2.1

14 + 2.1 = 16.1

This means the haircut would cost a total of $16.10.
