The factor of the polynomial 18x³ + 6x²y - 9x² - 3xy will be 3x(6x² - 2xy - 3x - y). Then the correct option is C.
<h3>What is a factorization?</h3>
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The polynomial is given below.
⇒ 18x³ + 6x²y - 9x² - 3xy
Then the factor of the polynomial will be
⇒ 18x³ + 6x²y - 9x² - 3xy
⇒ 3x(6x² - 2xy - 3x - y)

no real solutions
The conditions for the discriminant are
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then no real solutions
X will be the speed of species b and 4x will be the speed of species a:
x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h
If species b has a speed of 36 m/h, the speed of species a is 4 times that:
4 x 36 = 144 m/h.

Hope it helped,
Happy homework/ study/ exam!
Answer:
3
Step-by-step explanation:
1. Write out the equation
2. Subtract 6 from each side
3. Divide by 4 on each side
Answer:
16
Step-by-step explanation:
Order of operations goes:
1. Solve any problems inside parenthesis or brackets
2. Solve any exponents
3. Solve any multiplication or division from left to right
4. Solve any addition or subtraction from left to right
In this case, we'll need to solve the problem inside of the parenthesis first. Since there are no exponents or multiplication/division problems inside, we'll move on to addition and subtraction from left to right.
4 x (4 - 4 + 4)
4 x (0 + 4)
4 x 4
Now, we multiply
4 x 4
16
