What does x equal in this equation? 2x^{2} -7x+9=0
snow_tiger [21]

Answer:

Step-by-step explanation:                                    -b ± √(b² - 4ac)

Let's solve for x using the quadratic formula x = ------------------------

                                                                                          2a

In this case the coefficients are 2, -7 and 9, so the discriminant, b^2 - 4ac, is (-7)^2 - 4(2)(9), or 49 - 72 = -23.

The roots (zeros) of this quadratic are thus:

       -(-7) ± i√23

x = ----------------------

                 4

or

        7 ±i√23

x = -------------------

               4

1.The area of the KM 89 Farm in San Vicente is (x²+7x +12) sq meters. If its width is (x + 3) meters, what is the length of the
OLga [1]

Step-by-step explanation:

1. A = lw

  • l = A/w
  • l = (x²+7x +12) / (x + 3) =
  • (x + 4)(x + 3)/(x + 3) =
  • x + 4 m

2. V = lwh

  • lw = V/h
  • lw = (x³ + 12x²+ 47x + 60) / (x + 3) =
  • (x³+ 3x² + 9x² + 27x + 20 x + 60) /(x + 3) =
  • (x + 3)(x² + 9x + 20) / (x + 3) =
  • x² + 9x + 20 cm²

3. A = bh

  • h = A/b
  • h = (f³-8) / (f-2) =
  • (f - 2)(f² + 2f + 4)/(f-2) =
  • f² + 2f + 4 cm

4. A = p*c

  • c = A/p
  • c =  (3x³- 4x² + 2x + 4) / (x²- 2x + 2) =
  • (3x³ - 6x² + 6x + 2x² - 4x + 4) /(x² - 2x + 2) =
  • (x² - 2x + 2) (3x + 2) / (x² - 2x + 2) =
  • 3x + 2 cans

5. A = lw

  • l = A/w
  • l = (x² + 5x - 6)/(x + 2) =
  • (x - 1)(x + 6)/(x + 2) m

Who runs the fastest ? (ONLY ANSWER IF YOU KNOW IT BECAUSE CORRECT ONE GETS BRAINLIEST)
Genrish500 [490]

Answer:

<u><em>Stephanie runs the fastest per second: 14 feet per second</em></u>

Step-by-step explanation:

To find the fastest speed, you need to see which person runs the most per second:

Stephanie runs <em>14 feet per second</em>

<em />

Brooke runs 589 feet in 44 seconds.

Find the amount of feet per second by dividing:

\frac{589}{44} =13.4

Brooke runs about <em>13.4 feet per second</em>

<em />

Will runs 1 mile in 454 seconds.

Convert the miles to feet:

There are 5,280 feet in a mile. If Will runs 5,280 feet in 454 seconds, divide to find how much he runs per second:

\frac{5280}{454}= 11.6

Will runs about <em>11.6 feet per second.</em>

<em />

Rob runs 548 feet in a minute.

Convert the minute into seconds. There are 60 seconds in a minute. Divide the feet by the seconds to find how fast he runs per second:

\frac{548}{60}= 9.1

Rob runs about <em>9.1 feet per second.</em>

Stephanie runs 14 feet per second, the fastest time:

| 14 |, 13.4, 11.6, 9.1

<em>Finito.</em>

A department store buys 500 shirts at a cost of $3,500 and sells them at a selling price of $10 each. Find the percent markup.​
Ratling [72]

Answer: 30 percent.

Step-by-step explanation: First do 3,500 divided by 10 to find the cost of each shirt. Second subtract 7 from 10 which is 3. Then divide 3 by ten because you always divide by the amount being paid for. So 3 divided by 10 is .3 then multiply .3 by 100 which is 30 and that is your percent markup
