Isamu has the square tile below. each side is 1/3 foot. what is the area of the tile in square feet. isamu put 4 of the tiles together to make a square. write and solve an equation to find the area in square feet, of the square.

Part a) The area of the tile is

Part b) The area of the tile is

Step-by-step explanation:

Part a) What is the area of the tile in square feet?

we know that

The area of a square is equal to

where

b is the length side of the square

we have

substitute the value

Part b) Isamu put 4 of the tiles together to make a square. Write and solve an equation to find the area, in square feet, of the square

we have that

The new length side of the tile is

the new area is equal to

the answer is 8/21

hope this

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
