Question

Hiro painted his room. After 3 hours of painting at a rate of 8 square meters per hour, he had 28 square meters left to paint.

Answer 1

Answer:

8*3 = 24 + 28 = 52 total square feet

Step-by-step explanation:

The is painting at 8 sq m per hour

so A(t) = -8t +52

Answer 2

Answer: The total area that he is painting is equal to 52m^2, The area that is given is the slope (8m^2/h) and the initial value of y(x) when x = 3 hours.

Step-by-step explanation:

The rate is 8 m^2 per hour. This means that in one hour, Hiro paints 8 m^2.

We know that he has 28 m^2 left to paint.

then we have that:

Y(3hours) = 28m^2

Then, we initially had a total area of:

Y(0) = 28m^2 + 3*8m^2 = 52 m^2

Where the thing i did is add the area he has left and the area he painted in the 3 hour he was painting.

The total area of the room is 52m^2
