Please factor completely: <br><br> 20x^2 - 102x + 54
Temka [501]

Answer:

The answer to your question is 2(x - 9/2)(x - 3/5)

Step-by-step explanation:

Polynomial           20x² - 102x + 54

Process

1.- Find the Greatest Common Factor

                            20   102   54   2

                             10     51    27  2

                              5      51    27  3

                              5      17      9  3

                              5       17     3  3

                              5       17      1  5

                               1       17         17

                                         1

GCF = 2

2.- Factor 2

                        2(10x² - 51x + 27)

3.- Factor   10x² - 51x + 27

Use the general formula to solve this equation

                        x = \frac{-b +- \sqrt{b^{2} - 4ac}}{2a}

a = 10   b = -51   c = 27

                        x = \frac{51 +- \sqrt{51^{2} -4(10)(27)}}{2(10)}

-Simplification

                       x = \frac{51 +- 39}{20}

-Result

                        x₁ = 9/2       x₂ = 3/5

                       (x - 9/2)        (x - 3/5)

4.- Answer

                      2(x - 9/2)(x - 3/5)

Chris invests $20,000 into a savings account that accrues 5.2% interest compounded semiannually. What is the balance of Chris' a
il63 [147K]

The amount to be paid after 3 years is  $23,329.97.

<h3>What is Compound Interest?</h3>

In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.

Given:

P= 20,000

r= 5.2%

t= 3 years

r = R/100

r = 5.2/100

r = 0.052 rate per year,

Now, solve for A

A = P(1 + r/n)^{nt

A = 20,000.00(1 + 0.052/2)^{(2)(3)

A = 20,000.00(1 + 0.026)^(6)

A = $23,329.97

Which expression is equivalent to -5 7/8?
Bond [772]

Answer:

The answer is b) -5+ -7/8

Step-by-step explanation:

It is this answer because remember a negative plus a negative equals a negative, so when you add the too negative numbers together you get a negative answer.

EXAMPLE:

5 + 7/8 = 5 7/8

-5 + -7/8= -5 7/8

I'm positive it is correct
