Which expressions can you form by rearranging x+x+x+1+1+1+1+(-1)+(-1)+(-1)+(-x) Check all that apply. A) x – x + 2x – 2 + 4
B) 3x + 4 – 3 – x
C) 4x + 1
D) 2x + 1
E) 2x + 4 – 3

The correct options are;

B) 3x + 4 – 3 – x

D) 2x + 1

E) 2x + 4 – 3

Step-by-step explanation:

Which expressions can you form by rearranging x+x+x+1+1+1+1+(-1)+(-1)+(-1)+(-x) Check all that apply.

A) x – x + 2x – 2 + 4

B) 3x + 4 – 3 – x

C) 4x + 1

D) 2x + 1

E) 2x + 4 – 3

x+x+x+1+1+1+1+(-1)+(-1)+(-1)+(-x)

positive sign  multiply by negative sign will give a negative sign, hence;

x+x+x+1+1+1+1-1-1-1-x

Rearranging the equation;

x + x + x -x+ 1+1+1+1 -1-1-1

=3x -x + 4 -3

=2x + 1

We can also re-arrange it to give 3x + 4 - 3 -x

because

3x + 4 -3 -x

=3x -x + 4 -3

=2x + 1

Also, we can re-arrange it to give 2x + 4 - 3

since 2x + 4 - 3 = 2x + 1

The correct options are;

B) 3x + 4 – 3 – x

D) 2x + 1

E) 2x + 4 – 3

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
