Query With AND

I need the syntax for a Query with 'AND' for c#. See below:

EntityQuery eq = new EntityQuery

{

TypeName = "task",

Fields = new string[] { "name", "Project.Name", "C_TaskGroup", "PercentCompleted", "DueDate", "C_TaskParent" },

Where = new Compare

{LeftExpression = new FieldExpression { FieldName = "C_TaskGroup" },

Operator = Operator.Equal,

RightExpression = new ConstantExpression { Value = new EntityId { TypeName = "C_GenericTaskTaskGroup", Value = "Storyboards" }}

AND

...second simple query such as State = 'active'

}

}
