**Answer:**

**Surface area = 505cm²**

**Step-by-step explanation:**

Surface area of the triangular prism. = 2B + ph

B is the base area

p is the perimeter of the triangle

h is the height of the triangle

Base area = 1/2 * base * height

Base area = 1/2 * 18 * 40

Base area = 9 * 40

**Base area = 360cm²**

Perimeter of the triangle = 41 + 41 + 18

Perimeter of the triangle = 100cm

height of the prism = 45cm

Surface area = 360 + 100 + 45

**Surface area = 505cm²**

Divident =divisor × quotient + remainder

24= divisor ×(divisor-2)+0

d^2-2d-24=0

d=6 or -4

quotient is 4 of -6

so there are two possibilities, 6 or -4

**Answer:**

B.) 24

**Step-by-step explanation:**

1/3 of 48 is 16. 48-16=32. 1/2 (remaining tickets) of 32 is 16. 16+8 (tickets won)=24.

B.) 24
