Step-by-step explanation:
16x+4x-20=0
20x-20=0
bring -25 to other side it will become 25

The area <em>A</em> of a triangle is given by the formula
where <em>b</em> is the base and <em>h</em> is the height of the triangle.
From the graph, we can see that the base is 3 units and the height is 4 units. Therefore, the area of the triangle is

Answer:
-4
Step-by-step explanation:
Using a number line can help solve this problem
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1
To add a positive number to a negative one, we are going to move that number of spaces to the right (We are adding positive 3 to negative 7, so we are moving 3 spaces to the right)
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1
^ We start here at negative 7
-10 -9 -8 <em>-7</em><em> </em>-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1
^ ^ ^ Then move three to the right
-10 -9 -8 -7 -6 -5 <u>-4</u> -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1
So -4 is our answer
