Combining like terms with negative coefficients<br><br> −n+(−4)−(−4n)+6
Serjik [45]
Remember, if you add negative four, you're really subtracting four, or if you take away negative four, you're really adding four.

-n+(-4)-(-4n)+6
-n-4+4n+6 simplify
{-n+4n are like terms, so combine them. -n+4n is exactly the same as 4n-n, so flip them around if it helps. Just remember to keep the sign with the right number. Same thing with -4+6.}

Answer:

3n+2

In the following shape, two semicircles
Andrei [34K]

Answer:

The length around the figure in terms of r is 2r (\pi + 4).

Step-by-step explanation:

The perimeter of an object is the total length of the boundary of the object.

The figure consists two similar semicircle and a rectangle.

Adding the two semicircles, a complete circle is formed. The circumference of a circle = 2\pir.

The rectangle has a length which is twice its height.

     i.e l = 2h

But,

     r = \frac{h}{2}  (the diameters of the semicircles equal the height of the rectangle)

   ⇒ h = 2r

Thus, one side length of rectangle = 2 × 2r        (l = 2 × h)

                                                          = 4r

The length around the figure in terms of r is:

                   = 2\pir + 4r + 4r

                   = 2\pir + 8r

                   = 2r (\pi + 4)

The length around the figure in terms of r is 2r (\pi + 4).
