How many 4inch by 8inch bricks are needed to build a walk 6 feet wide and 24 feet long

The number of bricks needed to build area of a walk is 648 .

Step-by-step explanation:

Given as :

The dimension of bricks is 4 inches by 8 inches

The Length of bricks = L = 4 inches

The width of bricks = w = 8 inches

So, Area of bricks = Length of brick  × width of brick

Or,  Area of bricks = 4 × 8

I.e  Area of bricks = 32 inches²

Again

The dimension of walk is 6 feet by 24 feet

The Length of walk = l = 6 feet = ( 6 × 12 ) inches

I.e Length of walk = 72 inches

The width of walk = 24 feet = ( 24 × 12 ) inches

I.e width of walk = 288 inches

So, Area of walk = Length of walk  × width of walk

Or,  Area of walk = 72 × 288

I.e  Area of walk = 20,736 inches²

Now , Let The number of bricks needed to build walk = n

So, n =

I.e n =

∴   n= 648

So, number of bricks needed = n = 648

Hence The number of bricks needed to build area of a walk is 648 . Answer

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

i think the correct option is the second option.
