40 students makes for the DJ.
20 students makes for the decorations.
300 students makes for the profit.
so there was 360 students that went to the dance.
4(2x5 + 3) - 4(2) + 2(5).
4(13) - 18.
52-18 = 34.
Answer:
see below
Step-by-step explanation:
(2x + i)(2x – i)
FOIL
first 2x*2x =4x^2
outer -i * 2x = 2x i
inner i * 2x = 2x i
last i * -i = -i^2 and i^2 = -1 so - (i^2 ) = - (-1) = 1
Add together
4x^2 + 2xi -2x i +1
Combine like terms
4x^2 +1
Answer:
Number of additional inches= x
Number of additional topping= y
Total cost= 8+1.5(x)+0.75(y)
- cost of pizza= 8+1.5x+0.75y
