Which expressions is equivalent ?
agasfer [191]
<h3>3 Answers: Choice C, Choice D, Choice F</h3>

What these expressions have in common is that their exponents multiply to 16

  • (-4)*(-4) = 16 for choice C
  • (-2)*(-8) = 16 for choice D
  • 8*2 = 16 for choice F

The rule used here is (a^b)^c = a^(b*c). We multiply the exponents and keep the base the same.

What is the height of a solid box that has a mass of 438 g, a destiny of 2.17 g/cm, a length of 40 cm, and a width of 20 cm.​
lapo4ka [179]
  • <em>Answer:</em>

<em>h ≈ 0.25 cm</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there !</em>

  • <u><em>density formula</em></u>

<em>d = m/V</em>

<em>V = l×w×h</em>

<em>replace</em>

<em>2.17 = 438/(40×20)×h</em>

<em>2.17 = 438/800×h</em>

<em>2.17×800×h = 438</em>

<em>1736h = 438</em>

<em>h = 438/1736</em>

<em>h ≈ 0,25 cm</em>

<em>Good luck !</em>
