A juggler tosses a ball into the air. The balls height, h, feet and time, t, seconds can be represented by the equation h(t)=-161? +144. Part A: After 15 seconds what was the height of the ball?

Part B: Suppose the juggler misses the ball. At what time did the ball reach the ground?

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
