Answer:
A. 10
Step-by-step explanation:
The perimeter is the sum of all the outside lengths
Therefore, to find the value of x, you must do:
x + x + 5 + x + 7 = 42
3x + 12 = 42
3x = 30
x =10
The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method
The given equation is 
<u><em>Solving the equation using </em></u><u><em>Natasha's</em></u><u><em> method </em></u>
the fist step is to multiply by 2
x + 24 = - 6
The second step is to combine and add similar terms
x = -24 - 6
x = -30

<u><em>Second method of solving the equation</em></u>
The equation the friends are trying to solve is 
The first step is to combine similar terms
= - 8 - 2
The second step is to add similar terms together
= - 10
The third step is to multiply both sides of the equation by 3
x = (-10 x 3)
x = -30

Answer:
Number line 3 also known as [C]
Step-by-step explanation:
<em>Given that:</em>
<em>c ≤ </em>-1
Knowing that:
≤ = Less than or equal to
Now substitute into the equation:
C less than or equal to -1
Thus, it going left on a number line.
The only number line with left is [A] and [C]
Since ≤ = Less than or equal to -1
then, it including -1
also known as a closed circle means the number is included and an open circle means it is not.
Hence, it closed circle.
Thus, the answer is [C]
