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)

The balance in Beth's checking account is $75. She must deposit enough money in her account to be able to pay the electric bill,

Evgen [1.6K]

75+d=110 subtract 75 from both sides

d=$35

So she needs to deposit at least $35 to be able to pay the electric bill.

Shonda’s car gets an average of 27 miles per gallon. Gas costs $2.25 per gallon and she drives 892 miles to get from Baltimore,

bekas [8.4K]

She will spend $74.25 on gas.

Step-by-step explanation:

Given,

27 miles = 1 gallon

1 mile = $\frac{1}{27}\ mile$

Distance to cover = 892 miles

We will multiply this number with gallons of gas used for 1 mile.

892 miles = $\frac{1}{27}*892$

892 miles = 33.04 gallons of gas

Rounding off to nearest whole number;

892 miles = 33 gallons

Cost of one gallon of gas = $2.25

Cost of 33 gallons = 2.25*33 = $74.25

She will spend $74.25 on gas.
