To get the product of (3a + 2) and (4a² - 2a + 9), we can apply the rules of distribution over multiplication and have
3a(4a² - 2a + 9) + 2(4a² - 2a + 9)
12a³ - 6a² + 27a + 8a² - 4a + 18
Adding like terms of the same degree, we can simplify it into
12a³ + 2a² + 23a + 18
Therefore, the answer is D<span>.

Oman is wrong, if you raise any decimal number less than one to a power of 2 the number just gets smaller
Answer:
2 kg.
Step-by-step explanation:
F = m * a (Newton's Second Law of Motion).
10 = m * 5
The mass m = 10/5 = 2 kg.
Answer:
3x3
Step-by-step explanation:
G is a 3 x 4 matrix and His a 4x 3 matrix
In multiplication of matrix a particular formula is used
If G = MN and H = NM then GH = MM
So G= 3x4 and H = 4x3
Then GH = 3x3
The above rule is a rule that binds matrix multiplication and allows for an easier calculations and also helps check the possibility of the multiplication.
As for the above, the multiplication is possible an the result of the multiplication will give us a 3x3 matrix
Answer:
In order, your numbers are
22, 45, 75, 89, 89, 95, 100
The median is the number that is in the middle numbers of all your numbers. The median is 89, since it is in the very middle.
The mean is all your numbers added together and then divided by how ever many numbers you have. 22 + 45 + 75 + 89 + 89 + 95 + 100 = 515. Since you have 7 numbers, you would divide 515 by 7, which equals 73.5. The mean is 73.5.
The mode is the number that has the most numbers(not sure how to word it) Since 89 has two of the numbers, and no other numbers have duplicates, your mode is 89.
