Which equation is true?

ch4aika [34]

Answer : $9x^2 - 25 = (3x - 5)(3x + 5)$

(1) $9x^2 - 25 = (3x - 5)(3x - 5)$

Use FOIL method to mulitply (3x – 5)(3x – 5)

$(3x - 5)(3x - 5) = 9x^2 - 30x + 25$

(2) $9x^2 - 25 = (3x - 5)(3x + 5)$

Use FOIL method to mulitply (3x - 5)(3x + 5)

$(3x - 5)(3x - 5) = 9x^2 - 15x + 15x - 25 = 9x^2 - 25$

(3) $9x^2 - 25 = -(3x + 5)(3x + 5)$

Use FOIL method to mulitply -(3x + 5)(3x + 5)

$-(3x + 5)(3x + 5) = -(9x^2 + 30x + 25) = -9x^2 -30x -25$

(4) $9x^2 - 25 = -(3x + 5)(3x - 5)$

Use FOIL method to mulitply -(3x + 5)(3x - 5)

$-(3x + 5)(3x - 5) = -(9x^2 - 25) = -9x^2 + 25$

So equation 2 is true

Student Council sells bottled water at the cheerleading completion. At this rate, how many cases of bottled water would they sel

amid [387]

Answer:

Step-by-step explanation:

Lets find the rate of selling:

Let v= the rate of selling, b = number of bottles of water, and t = time:

b over t gives us the $v=\frac{b}{t}=\frac{3}{20}=\frac{6}{40}=0.15$ rate of selling:

3 hours is 60min * 3 = 180 mins, and since v=b/t, vt=b:

(0.15) * 180 = 27 bottles of water
