If we let x and y represent length and width, respectively, then we can write equations according to the problem statement.
.. x = y +2
.. xy = 3(2(x +y)) -1

This can be solved a variety of ways. I find a graphing calculator provides an easy solution: (x, y) = (13, 11).

The length of the rectangle is 13 inches.
The width of the rectangle is 11 inches.

______
Just so you're aware, the problem statement is nonsensical. You cannot compare perimeter (inches) to area (square inches). You can compare their numerical values, but the units are different, so there is no direct comparison.

What is √36ab^4c^5 ?
Zanzabum
You'll need to use parentheses to indicate what is under the first radical sign and what is not.  Did you mean radical(36a) or just radical 36?

I will assume that you meant radical(36a).

Then you have [radical(36a}*(b^4)*c^5.

This comes out to 6sqrt(a)*b^4*c^5.

Find the determinant of the matrix.
Jobisdone [24]

Answer:

-276

Step-by-step explanation:

We'll use the method of cofactors.  Use the coefficient +6 for

9   2

8   10

This gives you one third of the solution:  6 {(9)·(10) - (8)(2) },  or 444.

Next, use the coefficient 9, taking care to change the sign to -9  as follows:

     9   1

-9 |           |     =   -9(90 - 8) = -9(82) = -738  

      8  10

Finally with +2 as y our coefficient, evaluate the cofactor

9  1

9  2

ending up with  

+2(18-9) = +2(9) = 18

Finally add these three results together:

+444 - 738 + 18  =  -276

This, the determinant, D, is -276 (the fourth answer choice)

Mary is buying a case of water. She spends $7.99 for a case of 24 bottles. What is the unit rate? (Cost for 1 bottle) *
STALIN [3.7K]

Answer:

so I'm not 100% sure but in these types of questions you are supposed to divide

so you have a pack of 24 bottles for 7.99

so you would do 7.99÷24 = 0.33

then to check it you can multiply

0.33× 24 bottles and it gives you 7.93 which is super close to 7.99 anyway I hope this helps ...

Isabella works for a green house and is mixing food for the plants .in order to make one gallon of the mixture she needs 2/5 of
bonufazy [111]

Answer:

She will need 2 gallons of the food.

Step-by-step explanation:

If 1 gallon of mixture = 2/5 gallon of food, then 1 x 5 = 5 gallons of mixture, and 2/5 x 5 = 10/5 gallons of food. 10 divided by 5 is 2. Therefore, Isabella needs 2 gallons of food.
