Karen is painting the floor and 4 walls of her basement. Dimensions are 12m long, 4m wide and 2.5m high. One can of 4L paint covers 10m^2.

a) what surface area does she need to paint?

b) how many cans of paint does Karen need (show work).

HELP ASAP!!

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

How do i do this? i don’t understand

Are the corresponding angles congruent? explain why or why not.
