to raise money for her school field trip, Jane is selling candles. She has a large cancel for $8, and a small candle for $5. If
Fed [463]

Answer:

  • 45 large candles
  • 53 small candles

Step-by-step explanation:

Let c represent the number of large candles Jane sold. Then 98-c is the number of small candles. Her revenue is ...

  8c +5(98-c) = 625

  3c + 490 = 625 . . . . . . eliminate parentheses, collect terms

  3c = 135 . . . . . . . . . . . . subtract 490

  c = 45 . . . . . . . . . . . . . . divide by 3

Jane sold 45 large candles and 98-45 = 53 small candles.

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)
