Answer:
51 points
Step-by-step explanation:
45 - 40 + 81 - 35 = x
x = 51
The sum is 4x³ + 3x² + 2x – 6.
Solution:
The correct question is given below.
(4x³ – 2x² + 3x – 1) + (5x² – x – 5). What is the sum?
<u>To find the sum of the polynomial:</u>
Sum of (4x³ – 2x² + 3x – 1) and (5x² – x – 5)
= (4x³ – 2x² + 3x – 1) + (5x² – x – 5)
Remove the parentheses.
= 4x³ – 2x² + 3x – 1 + 5x² – x – 5
Group like terms together.
= 4x³ – 2x² + 5x² + 3x – x – 1 – 5
Add the similar elements. i.e the element with same power.
= 4x³ + 3x² + 2x – 1 – 5
Subtract the constant terms.
= 4x³ + 3x² + 2x – 6
The sum is 4x³ + 3x² + 2x – 6.
Answer:
To find the mean, you must add up all numbers in the problem, then divide the sum by however many numbers there are.
For example, 5, 8, 13, 17, 22.
The sum of these numbers is 65.
Because there are 5 numbers, you have to take 65 and divide that by 5.
65/5 = 13.
Your answer: You can use the numbers 26 and 38.
So, 36 + 28 = 64
Then, divide by 2.
64/2 = 32
