Answer:
Step-by-step explanation:
<u>The Sum:</u>
- 3x²y - 5a + 4b + (-9x²y - 7b + 4a) =
- 3x²y - 9x²y - 5a + 4a + 4b - 7b =
- -6x²y - a - 3b
<u>The difference:</u>
- 3x²y - 5a + 4b - (-9x²y - 7b + 4a) =
- 3x²y + 9x²y - 5a - 4a + 4b + 7b =
- 12x²y - 9a + 11b
<u>Subtract the sum from the difference:</u>
- 12x²y - 9a + 11b - (-6x²y - a - 3b) =
- 12x²y + 6x²y - 9a + a + 11b + 3b =
- 18x²y - 8a + 14b
Answer:
answer is A
Step-by-step explanation
Those lines pointing down to each angle means there both equal
<span>The number of different permutation of n number of objects can be written as nPr.</span>
6 x 5 x4 in nPr is 6P4 = 6! / (6-4)! or 6 x5 x4
√(75m^3b
Whenever you are looking to simplify a radical, you want to see what the prime factorization of the elements under the radical...
√(3*5*5*m*m*m*b) now you can move out the squared terms (we move out all of the terms that appear twice in this case(
5m√(3mb)
<u>Answer:</u>
length = 39 inches
width = 11 inches
<u>Step-by-step explanation:</u>
Assuming the length of the rectangle to be l and width to be w, we can write the length as:
We know that perimeter of the rectangle is 100 inches and its formula is:
<em>Perimeter of a Rectangle = 2l + 2w</em>
So substituting the given values in the above formula:
Substituting this value of w to find the length l:
Therefore, the length = 39 inches and width = 11 inches.
