Carmen bought a plant that is 4 centimeters tall. Each Week the plant grows an additional 2 centimeters. Write an expression to show the height of the plant after W weeks

The expression is 4+2xw=

Let h represent the height of the plant after a certain amount of weeks

let w represent the number of weeks

h = 4 + 2w

explanation: 4 never changes but the variable which is w will affect the growth - per week, so we use w. If its 3 weeks then you do 4+2 (3) and you get 10cm.
