One factor of the polynomial 3x3 + 20x2 - 21x + 88 is (x + 8). what is the other factor of the polynomial? (note: use long divis

Snezhnost [94]

The other factor of the polynomial is a. 3x2-4x+11

Given polynomial is 3x3 + 20x2 - 21x + 88 and the factor is (x+8)

We need to find another factor using long division method

So,

We will divide the polynomial by the factor to find the another factor

Therefore,

$\sqrt[x+8]{3x^3+20x^2-21x+88}$

Now calculating

First multiplying $3x^2$ with (x+8) so , $3x^2$ will be in the quotient

We get $3x^3+24x^2$

simplifying the calculation for $3x^3+20x^2$ and $3x^3+24x^2$

We get the remainder is $-4x^2-21x+88$

Second we will multiply -4x with (x+8) Where -4x will be in the quotient

We get $-4x^2-32x$ and then we will simplify the equation

We get 11x +88 as a remainder

The quotient we get is $3x^2-4x$

Third we will multiply +11 with (x+8) Where +11 will be in the quotient

we get 11x+88

Simplifying the equation we get the remainder 0

So the quotient we get is (3x2 - 4x+11)

Hence the another factor of the polynomial is (3x2 - 4x+11)

Alarger number is 2 more than 4 times a smaller number. The larger number is also 8 more than 2 times the smaller number. 4x+2 y

Umnica [9.8K]

Answer:

the value of the smallest number is 3

Step-by-step explanation:

The computation of the value of the smaller number is shown below:

Given that

y = 4x + 2

y = 2x + 8

Now equate these two equations

4x + 2 = 2x + 8

4x - 2x = 8 - 2

2x = 6

x = 3

Hence, the value of the smallest number is 3

The same is to be considered

skad [1K]

Answer: Hello your question is incomplete attached below is the missing

n ( 1 + n )

Step-by-step explanation:

P( Bob hits target ) = 1/3

P( Eve hits target ) = 2/3

P( Carol hits target ) = 1

<u>Compute the P that Bob wins in a duel against Eve alone</u>

P(Bob hits the target in first shot ) = n = 1/3

P(Bob hits the target in second shot ) = n^2 = ( 1/3 * 1/3 ) = 1/9

hence the probability of Bob winning( i.e. P( Bob wins Event E1 ) = n + n^2 = n ( 1 + n )
