A rectangle is 6 tiles wide by 12 tiles high. How many
tiles are in the rectangle?
Show your work.

Well it’s 2d and how many tiles in the rectangle is an area question

In this case we just multiply since w*l is area but in this case width is 6 and length (height) is 12

so 6*12= 72

72 tiles

Step-by-step explanation:

Here you have to multiply. Why?

Think of a graph. To find the area we need to use the formula length times width. (a = l x w)  So we use 6 tiles wide and 12 tiles high as out length and width.

6 = width

12 = length

Now multiply

6 x 12 = 72

Hope this helps! Please comment if it does or not and if it needs adjustment. :)

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
