9x3
5x3 – 8x2
9x3 – 8x2
Answer: Last option is correct.
Step-by-step explanation:
Since we have given that
We need to find the sum of the polynomials:
So, we first collect the like terms:
Hence, the sum of polynomials is
Therefore, Last option is correct.

Step-by-step explanation:
B—> Graph A, Step B
Explanation
(x + 9)(x - 1)
(x + 9)(x + 1)
(x - 9)(x - 1)
Prime
The factors of the expression are (x - 9) (x + 1).
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the liketerms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
x² - 8x + 9
Determinantformula.
a = 1, b = -8, c = 9
So,
x = -b ± √(b² - 4ac) / 2a
x = 8 ± √(64 - 36) / 2
x = 8 ± √100 / 2
x = 8 ± 10 / 2
x = 4 ± 5
x = 4 + 5 and x = 4 - 5
x = 9 and x = -1
x - 9 = 0 and x + 1 = 0
Now,
The tworoots are (x - 9) and (x + 1).
Thus,
The factors of the expression are (x - 9) (x + 1).

What is the dozens?
A dozen (doz or dz) is a set (or group) of items. Groupings of twelve are thought to be one of the earliest primitive groupings
Here given that,
children play baseball on Friday. children play on Saturday.three dozens of the children are boys.
Firstly, we add
As we know in dozen = , so
So, the total is .
Hence, the children play baseball in all is .
