Answer:
6
Step-by-step explanation:
To calculate <em>x+10</em>, we first need to find <em>x</em>. To do this, we can use the first equation.
We are given the equation:

To solve for <em>x</em>, turn one side of the equation into 0 and solve. Therefore:

So, the possible values for <em>x</em> are -4 and 12.
However, we are also told that <em>x<0</em>. In other words, <em>x</em> must be negative. Thus, we can remove 12. That leaves us with: <em>x=-4. </em>
So:

The answer is either B or D but I believe it is B

Answer:
Answer is 105 in^2
Step-by-step explanation: Area of rectangle= length X breadth
= 8X12
=96in^ 2
Area of triangle= 1/2 X base X height
= 1/2 X 3 X 6
= 9 in^2
Area of irregular pentagon = area of triangle + area of rectangle
= 96+9
=105 in ^2
