Answer:
Step-by-step explanation:
The formula to work out the area of a triangle is :
to find the volume of this shape you would first need to work out the area of the triangle. You can do this by first multiplying the base of 6 by the height of 8, this gives you 48. The next step in working out the area is to divide 48 by 2, this gives you 24. This is because by multiplying the base by the height you are working out the area of a square with the same dimensions, and so will need to be divided by 2 to work out the area of the triangle. Now that you have worked out the area you can now work out the volume. To do this you would simply multiply the area of 24 by the height of 13, this gives you 312.
<u>Working out the area:</u>
1) Multiply 6 by 8.
2) Divide 48 by 2.
<u>Working out the volume:</u>
<u></u>
1) Multiply 24 by 13.

To solve for 'x' we need to isolate it, by getting all terms with 'x' on one side of the equation and all terms without 'x' on the other side.
To do this we can start by subtracting 51 from both sides of the equation:
Now we need to 'move' the -14 over as well. We can do this by dividing both sides by -14:
We now have 'x' isloated and out answer is there: X= -(33/14)
We can check this answer by plugging it back into the original equation:
