Find the total square footage of each room. The room will be a rectangle and finding the area of a rectangle is just the length times the width
area of rectangle = lw
area of each room = 14 x 20.5 = 287 ft^2
The 4 rooms each have the same square footage.
Total square footage of all rooms = 287 x 4 = 1148 ft^2
To find how many roles of carpet are needed, divide the footage needed to be covered by the footage per carpet
1148/200 = 5.74
You can't buy 5.74 of a carpet roll, so you will need 6 rolls :)
Hope I helped
Answer:
The system has one solution.
Step-by-step explanation:
To find the number of solutions of the system, we equal both equations for y.
If we have ax = b, in which both a and b are different of 0, we have one solution.
If both a and b are 0, we have infinite solutions.
If a is 0 and b is not, there are no solutions.
y=6/7x-8 and y=7/9x+10/9
So





Both a and b are different of 0, so the system has one solution.
Answer:
-64
Step-by-step explanation:
The question is asking to solve 
Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.
is the same as -4 · -4 · -4
First let's figure out if this will be negative or positive
Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive
Now find out what 4 x 4 x 4 equals (64)
In conclusion the answer is -64
