Answer:

x = 0

Step-by-step explanation:

9x - 7 = -7

  • Add 7 on both sides so that 9x can be isolated

9x - 7 + 7 = -7 + 7

9x = 0

  • Divide by 9 on both sides so x can be by itself

9/9x = 0/9

x = 0

If sample bias exists, then we can easily trust using the sample as representative of the
Lina20 [59]
<h3>Answer:  False</h3>

Explanation:

If the sample is biased, then it does not represent the population. A biased sample favors one or more groups over others.

For example, if the sample consisted of only men, then the sample is biased toward men and leaves out women from the group. Hence, this sample does not represent everyone.

2(n+7)=14+2n and 1-x=7x-(8x-6)
myrzilka [38]
2n+14=14+2n so this one as an infinite number of solutions. The second one 1-x=-x-6 so you add x on both sides which results in it having no solutions.

I need help on this anyone
DanielleElmas [232]

Perimeter = 2L + 2W

Perimeter = 2(4x^2) + 2(y^2)

Perimeter = 8x^2 + 2y^2

x^2 - 7x^2 = -6x^2

-3x - -2x = -3x +2x = -x

8 - -1 = 8+1 = 9

Answer = -6x^2 -x + 9

9x^2 -4x - 3x^2 -2x

9x^2 - 3x^2 = 6x^2

-4x - -2x = -4x +2x = -2x

Answer = 6x^2 -2x
