3-(x+1)=3-x-1

(+3)-(x+1)

(+3)-1(x+1)

Distribute the -1 to (x+1)

(+3)-1x-1

3-x-1

-x+2

3-1(x+1) = 3-x-1

Step 1. distribute the negative sign

2(-x-1) = 3-x-1

Step 2. distribute the 3

-2x-3= 3-x-1

add 3 on both sides

-2x = 6 - x - 1

add x to both sides

-1x = 6 - 1

-1x=5

x=5

SO..... u have to plug 5 in

PLZ ANSWER THANK YOU
NikAS [45]

Answer:

1, x/3, x^2/9, x^3/27,  x^4/81


x^4 +3x^3+9x^2+27x+81

----------------------------------------

81


Step-by-step explanation:

(x/3) ^i

i=0   (x/3)^0 = 1

i=1   (x/3)^1 = x/3

i=2   (x/3)^2 = x^2/3^2 = x^2/9

i=3   (x/3)^3 = x^3/3^3 =x^3/27

i=4   (x/3)^4 = x^4/3^4 =x^4/81

The sum is

1+(x/3) + x^2/9 + x^3/27 + x^4/81

We need a common denominator of 81

1*81/81 + x/3 *27/27 + x^2/9 *9/9 + x^3/27 *3/3 + x^4/81

81+27x + 9x^2 + 3x^3 +x^4

----------------------------------------

81

Rewriting from largest power to smallest power

x^4 +3x^3+9x^2+27x+81

----------------------------------------

81

Hey<3 If you help you’re amazing if you don’t you’re awesome.
OleMash [197]
<h3>Answer:  576 </h3>

============================================================

Check out the diagram below.

I've split the figure into 3 separate blocks. We calculate the volume of each block, then add up those volumes to get the final answer.

  • Block A = largest block on the left
  • Block B = middle block
  • Block C = smallest block on the right

So,

  • volume of block A = length*width*height = 6*6*8 = 288 ft^3
  • volume of block B = length*width*height = 6*6*5 = 180 ft^3
  • volume of block C = length*width*height = 6*6*3 = 108 ft^3

Therefore, the total volume we're working with is:

A+B+C = 288+180+108 = 576 cubic feet

The "cubic feet" or "ft^3" portion is already taken care of by your teacher, so you just need to type in the number itself.
