I need help with this it is very confusing.

Part A: 90 + 6x = 108

Part B: 3

Step-by-step explanation:

Part A:

Variable x = number of movie tickets purchased

18 × 5 + 6x = 108

90 + 6x = 108

Part B:

Variable y = number of people

18y + 1(7) = 61

18y + 7 = 61

18y = 54

y = 3

There were 3 people in this group.

where is the triangle?

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
