Stacy and neil painted 280 ft2 of their living room wall with 45 gallon of paint. how many square feet can they paint with 3 gallons of paint?

The number of square  feet that can be painted with 3 gallons of paint is 18.667 ft²

Step-by-step explanation:

Stacy and Neil painted 280 ft² of their living room wall with 45 gallon of paint.

To find the number of square feet that can be painted with 3 gallons of paint,

we will simply use proportion;

Let x = number of square feet that can be painted with 3 gallons of paint

280 ft²     =     45 gallons

   x           =       3 gallons

cross multiply

45  ×   x   =   280  ×    3

45x    =   840

Divide both-side of the equation by 45

45x/45   =  840/45

(on the right-hand side of the equation, 45 at the numerator will cancel-out 45 at the denominator leaving us with just x while on the right-hand side of the equation, 840 will be divided by 45)

x = 18.667 ft²

Therefore, the number of square feet that they can paint with 3 gallons of paint is 18.667 ft²

answer: h

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
