You have to combine like terms (terms that have the same variable(x,y....) and power/exponent)²³

(4x³ - 4 + 7x) - (2x³ - x - 8) Distribute -1 into (2x³ - x - 8)

(4x³ - 4 + 7x) + (-)2x³ - (-)x - (-)8 (two negative signs cancel each other out and become positive)

(4x³ - 4 + 7x) - 2x³ + x + 8 Now combine like terms

4x³ - 2x³ + 7x + x - 4 + 8 (I rearranged for the like terms to be next to each other)

2x³ + 8x + 4 It is equivalent to B

(-3x^2+x^4+x)+(2x^4-7+4x) Combine like terms

-3x^2+x^4+2x^4+x+4x-7 (I rearranged for the like terms to be next to each other)

-3x^2+3x^4+5x-7 It is equivalent to D

(x² - 2x)(2x + 3) Distribute x² into (2x + 3) and distribute -2x into (2x + 3)

(x²)2x + (x²)3 + (-2x)2x + (-2x)3

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together

2x³ + 3x² - 4x² - 6x Combine like terms

2x³ - x² - 6x It is equivalent to A

[Info]

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together. (You can combine the exponents only if they have the same variable)

For example:

$x^{2} (x^3)=x^{(2+3)}=x^5$

(y^3)x^2=y^3x^2 (You can't combine them because they have different exponents of y and x)

$(5^2)(5^4)=5^{(2+4)}=5^6=15,625$

Answer from: Quest

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

(round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up? (round your answer to 2 decimal places.)e will not show up. dave and mike do not know each other and their decisions can be assumed to be independent.
