Answer:

  • -5x+21
  • 22

Step-by-step explanation:

There are no factors outside the parentheses that need to be distributed, so the parentheses can be simply dropped:

  6 -2x +15 -3x

The terms can be rearranged to put like terms next to each other:

  -2x -3x +6 +15

and the like terms can be combined.

  -5x +21 . . . . simplified expression

__

Put the value of x where x is, then do the arithmetic.

  -5(-0.2) +21 = 1 +21 = 22

The area of a circle is 16cm2. What is the circle's circumference?
Delicious77 [7]
A=pir^2
c=2pir

a=pir^2=16
pir^2=16
divide both sides by pi or about 3.141592
r^2=5.0929581789406507446042804279205
sqrt both sides
r=2.2567583341910251477923178062431

circumference=2pir
circumference=2pi(2.2567583341910251477923178062431)
c=4.5135166683820502955846356124862pi
about 4.5pi square cm
