The label on a gallon of paint says that it will cover from 250 square feet to 450 square feet depending on the surface that is being painted. a painter has 12 gallons of paint on hand. the equation a 12c gives the area a (in square feet) that the 12 gallons of paint will cover if applied at a coverage rate c (in square feet per gallon).

The variable “c” is the independent variable so it is located on the x-axis. 
While the variable “A” is the dependent variable so it is located on the y-axis. 

Using the formula:

A = 12c

At c = 250, A = 3000. 
At c = 450, A = 5400. 

Now draw a point at coordinate (250, 3000), and another point at coordinate (450, 5400). Connect the 2 points with a line.

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
