Answer:
-2 sqrt(15)
Step-by-step explanation:
sqrt(-15) sqrt(-4)
We can use sqrt(ab) = sqrt(a) sqrt(b)
sqrt(-1) sqrt(15) * sqrt(-1) * sqrt(4)
We know the sqrt(-1) = i
i * sqrt(15) * i * 2
2i^2 sqrt(15)
i^2 = -1
-2 sqrt(15)
Let the number of pepperoni pizzas be x
pepperoni = x
veggie = x - 8 [<span>There were eight fewer veggie than pepperoni]
</span>combo = 3x [T<span>here were three times as many combo as pepperoni]
</span>
Given that the total Pizza: 112
x + x - 8 + 3x = 112
5x - 8 = 112
5x = 112 + 8
5x = 120
x = 24
x= 24
x - 8 = 16
3x = 72
So there were 24 pepperoni pizza, 16 veggie pizza and 72 combo pizza
