What is the factorization of 3x2 – 8x + 5?

ELEN [110]

we have

$3x^{2} -8x+5$

Equate the expression to zero to find the roots

$3x^{2} -8x+5=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$3x^{2} -8x=-5$

Factor the leading coefficient

$3(x^{2} -(8x/3))=-5$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$3(x^{2} -(8x/3)+(16/9))=-5+(16/3)$

$3(x^{2} -(8x/3)+(16/9))=(1/3)$

Rewrite as perfect squares

$3(x-(4x/3))^{2}=(1/3)$

$(x-(4x/3))^{2}=(1/9)$

square roots both sides

$(x-\frac{4}{3})=(+/-) \sqrt{\frac{1}{9}}$

$x=\frac{4}{3}(+/-) \frac{1}{3}$

the roots are

$x=\frac{4}{3}+ \frac{1}{3}=\frac{5}{3}$

$x=\frac{4}{3}- \frac{1}{3}=\frac{3}{3}=1$

$3x^{2} -8x+5=3(x-\frac{5}{3})(x-1)=(3x-5)(x-1)$

therefore

<u>the answer is the option</u>

$(3x-5)(x-1)$

Raise 7 to the 5th power, subtract the result from 9, then multiply what you have by c

goblinko [34]

Step 1.) 7^5 = 16,807
Step 2.) 9 - 16,807 = -16,798
Step 3.) -16,798 * c = -16,798c

i need help finding the height of a cone and i do not know where to start. any help will be greatly appreciated:))

Aliun [14]

Answer:

h=12

Step-by-step explanation:

First look at the formula for finding the volume of a cone- $V=\pi r^{2} \frac{h}{3}$

Next substitute any variables for values you already know- $144\pi =\pi (6)^{2} \frac{h}{3}$

Then solve the equation.

Rue Co.’s allowance for uncollectible accounts had a credit balance of $12,000 at December 31, Year 1. During Year 2, Rue wrote

klio [65]

Answer:

option B

Step-by-step explanation:

given,

allowance for uncollectible accounts had a credit balance = $12,000.

Rue wrote off uncollectible accounts = $48,000

The aging of accounts receivable indicated = $50,000

amount of uncollectible accounts expense = ?

credit balance - wrote off uncollectible account + account expense = account recievable

$12,000 - $48,000 + account expense = $50,000

account expense = $50,000 + $ 36,000

account expense = $86,000

amount of uncollectible accounts expense = $86,000

Hence, the correct answer is option B
