Answer:

p = 0.259264214

Nataliya [291]

Given:

  • The area of a rectangular painting is 7719 cm²
  • Width of painting = 83cm

To Find?

  • Length of painting.

Where,

  • Length = x cm
  • Breadth = 73 cm

→ 7719 = x × 83

→ x = 7719/83

→ x = 93 cm

Hence,

Factor completely. -5 x2y + 10 xy - 15 xy2<br><br> I need help.
ASHA 777 [7]

Answer:

5\,x\,y\,(-x+2-3y)

Step-by-step explanation:

Always proceed by first extracting all common factors to all terms:

Notice that the factors: 5, x, and y are present in all terms, so we can extract them from the trinomial:

-5x^2y+10xy-15xy^2\\5\,x\,y\,(-x+2-3y)

Now, the trinomial left (-x+2-3y) cannot be factored out, so then factoring is complete.
