X2-3xy-5xy-7y2+4x2+8y2
Zepler [3.9K]

For this case we must simplify the following expression:

x ^ 2-3xy-5xy-7y ^ 2 + 4x ^ 2 + 8y ^ 2

We must add similar terms taking into account that:

  • Equal signs are added and the same sign is placed.
  • Different signs are subtracted and the major sign is placed.

(x ^ 2 + 4x ^ 2) + (- 3xy-5xy) + (- 7y ^ 2 + 8y ^ 2) =\\5x ^ 2-8xy + y ^ 2

Thus, the simplified expression is:

5x ^ 2-8xy + y ^ 2

Answer:

5x ^ 2-8xy + y ^ 2

Since 18% is 18/100 you just have to multiply the $842.4 by the reciprocal of that to find your answer
Reciprocal of 18/100 is 100/18
842.4* 100/18 equals 84240/18

What is the answer, Shelby made 5 quarts of juice for a picnic. How many cups of juice did shelby make?
Anvisha [2.4K]

Given, Shelby made 5 quarts of juice for a picnic.

We know that 1 quart of juice = 4 cups of juice.

Here we will have to convert 5 quarts to cups.

As for 1 quart there are 4 cups, to find 5 quarts we have to multiply 4 times 5.

So 5 quarts of juice = (4)(5) cups of juice.

We know that, (4)(5) = 20

5 quarts of juice = 20 cups of juice.

We have got the required answer here.

Shelby made 20 cups of juice there in the picnic.
