Answer:
a) an expression for the number of groups formed by p people
number of groups formed = ![\frac{p}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bp%7D%7B4%7D)
b) How many groups are formed if there are 28 people
number of groups formed = ![\frac{p}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bp%7D%7B4%7D)
=28÷4
= 7
Answer: 7 groups

Answer:
x ≈ -7.73 , - 4.27
Step-by-step explanation:
x² + 12x + 33 = 0 ( subtract 33 from both sides )
x² + 12x = - 33
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = - 33 + 36
(x + 6)² = 3 ← take square root of both sides )
x + 6 = ±
( subtract 6 from both sides )
x = - 6 ± ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Then
x = - 6 -
≈ - 7.73 ( to the nearest hundredth )
x = - 6 +
≈ - 4.27 ( to the nearest hundredth )
