Does anyone know what the equation would be for this

i = 39m

The number of inches in 9 meters is 351.

Step-by-step explanation:

Divide the number of inches in each line by the number of meters.

39/1 = 39

78/2 = 39

117/3 = 39

156/4 = 39

Notice that every time you divide the number of inches by the corresponding number of meters, you always get 39. That means that multiplying the number of meters by 39 gives you the number of inches.

The equation is

i = 39m

We can test the equation to make sure it's correct.

Try 1 meter. Then we have m = 1. Plug in 1 for m in the equation:

i = 39(1)

i = 39

You get i = 39, which means that 1 meter equals 39 inches as the table stated.

Try 3 meters. Then we have m = 3. Plug in 3 for m in the equation:

i = 39(3)

i = 117

You get i = 117, which means that 3 meters equals 117 inches as the table stated.

Now that we know our equation is correct, we let m = 9 to find the number of inches equal to 9 meters.

i = 39m

i = 39(9)

i = 351

The number of inches in 9 meters is 351.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
