Answer:

36 squares.

Step-by-step explanation:

Number of squares in each step is triangular number. This form a triangular series.

1 , 3 , 6 , 10........

Number of squares in each step is given by

$\sf \dfrac{n*(n+1)}{2}$ here , n is the step or term.

n = 8

$\sf Number \ of \ squares \ in \ 8^{th} \ step = \dfrac{8 * (8+1)}{2}$

$\sf = \dfrac{8*9}{2}\\\\ = 4*9\\\\=36 \ squares$

Answer:

168/(x² +7x)

Step-by-step explanation:

The height of each window is 14/(x+7), and the width of each window is 12/x. The area of each window is the product of its height ans width:

area = (14/(x+7))(12/x) = 168/(x(x +7))

area = 168/(x² +7x)

_____

<em>Comment on the problem</em>

There is not enough information given to determine suitable values for x. If x is 42, each window is a square 3 3/7 inches on a side.

Answer:

This question is incomplete as no image was attached. Please find the missing image in the attachment. Also, this is the correct question:

Cal's go cart has a gas tank with the dimensions shown below. He uses a gas can that holds 1 gallon of gas, to fill the go cart tank. 1 gallon = 231 inches^3. How many full gas cans will it take to fill the go cart's gas tank?

Answer: 2 full gas cans

Step-by-step explanation:

From the image, we have the following dimensions:

length, l = 15.4 inches (in)

width, w = 10 in

height, h = 3 in.

The volume of the gas tank (which is rectangular) is given as:

$Volume = length * width * height = lwh\\\\Volume = 15.4 * 10 * 3 = 462 cubic inches = 462in^{3}$

NB: The unit of volume is cubic units. In this example, it is cubic inches.

The gas can being used to fill the tank holds 1 gallon of gas = $231in^{3}$

The total volume to be filled is $462in^{3}$ of gas.

So, it will take $\frac{462in^{3} }{231in^{3} } = 2$ full gas cans to fill the go cart's gas tank.

Therefore, the answer is 2.
