Answer:

  • 740 meters of fence
  • 22,000 square meters

Step-by-step explanation:

Two of the sides total 150 +220 = 370 meters. The other two sides are the same lengths, so the sum of lengths of the four sides is ...

  2·370 m = 740 m . . . . . length of fence needed

__

The area of a parallelogram is the product of base and height.

  A = bh = (220 m)(100 m) = 22,000 m^2 . . . . area the fence encloses

If f(x)=3x+10x and g(x)=4x-2 find (f+g)(x)<br> A:3x+6x+2<br> B:17x-2<br> C:3x+14x-2<br> D:3x-6x+2
Rudik [331]

Answer:

3x^2+14x-2 if you meant f(x)=3x^2+10x and g(x)=4x-2

and I think C was meant to read 3x^2+14x-2

Please correct me if I have mistranslated. Thank you kindly.

Step-by-step explanation:

I kind of wonder if you meant f(x)=3x^2+10x and g(x)=4x-2.

(f+g)(x)=f(x)+g(x)

          =(3x^2+10x)+(4x-2)

          =3x^2+10x+4x-2

          =3x^2+(10x+4x)-2  I paired 10x and 4x together because    they are like terms

         =3x^2+14x-2
