Concrete can be purchased by the cubic yard. how much will it cost to pour a slab 12 feet by 12 feet by 9 inches for a patio if the concrete costs $54.00 per cubic yard? since the final price is per cubic yard, i might convert everthing to yards from the beginning.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
