Mathematics

Answer:

12 and -12

Step-by-step explanation:

144 is a perfect square which means that a number multiplies to it with the same number. In this instance both 12 and -12 equal 144.

12 x 12 = 144

-12 x -12 = 144 (two negatives equal a positive)

Answer:

The square root function

sqrt(144) or √144 produces a single positive value, 12.  

However if you have an equation

x² = 144, then you have two possible values for x, 12 and -12.  

Two ways to look at it.  

x² - 144 = 0

Difference of two squares

(x+12)(x-12) = 0

x = -12, 12

x² = 144

x = ±√144

x = ±12

x = -12, 12

Audrey has $440 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
Afina-wow [57]

The number of outfits Audrey can purchase while staying within her budget is 2

<h3>Inequality</h3>

  • Amount Audrey has to spend at a bicycle store = $440

  • Cost of new bicycle = $259.52

  • Cost of each bicycle reflectors = $3.07

  • Total cost of bicycle reflectors = $3.07 × 2

= $6.14

  • Cost of a pair of bike gloves = $29.12.

  • Cost of each biking outfits = $72.61

  • Number of bicycle outfits = x

The inequality:

259.52 + 6.14 + 29.12 + 72.61x ≤ 440

294.78 + 72.61x ≤ 440

72.61x ≤ 440 - 294.78

72.61x ≤ 145.22

x ≤ 145.22 / 72.61

x ≤ 2

Therefore, the number of outfits Audrey can purchase while staying within her budget.

P=5(q-2r)/r<br><br> solve for r
Pavel [41]

Answer:

r = 5q / (p + 10)

Step-by-step explanation:

p = 5(q - 2r)/r

multiply both sides by r

pr = 5(q - 2r)

distribute

pr = 5q  - 10r

add 10r to both sides

pr + 10r = 5q

Factor out r

r(p + 10) = 5q

divide both sides by p + 10

r = 5q / (p + 10)
