Dani is helping her dad to organise a barbeque. They want an equal number of bread rolls, burgers and cheese slices.
- There are 18 burgers in each packet.
- There are 15 bread rolls in each packet.
- There are 12 cheese slices in each packet.
What is the smallest number of each packet that they can buy?

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
