How to evaluate the expression?</h3>
Here we have the expression:
6*(x - 5)
Which represents the product of 6 and the sum between x and negative 5.
We want to evaluate it in x = 7, that means just replacing the variable in the given expression by the number 7, and then solving the expression.
Let's do that:
6*(7 - 5) = 6*(2) = 12
In this way, we conclude that when we evaluate in x = 7, the given expression is equal to 12.

Answer:
On the farm there are 5 horses, 12 cows and 13 pigs
In this example, we are asked to find the perimeter of the trapezoid. The perimeter of a figure is the distance around the figure.
To find the perimeter of the trapezoid, all we have to do is add the lengths of the sides. In this case, we would add 3 + 5 + 3 + 9 = 20 cm.
<em>Therefore, the perimeter of the trapezoid is 20 cm</em>
