Answer: 5
Step-by-step explanation: When there is more than one term inside the absolute value, we first simplify inside the absolute value.
So here, our first step is to add -15 + 10 which is -5.
So we have ║-5║.
Now remember that absolute value means <em>distance from zero</em> on a number line. Since -5 is 5 units from zero, the absolute value of -5 is 5.
So the absolute value of -15 + 10 is 5.
Answer:
Perimeter: 33.7 mm
Area: 54 mm
Step-by-step explanation:
If you do 12 + 9.7 + 12 you will get the perimeter, and to get the area you would use the formula A = 
x base x height. Since the base is 12 and the height is 9, you would do 12 x 9 x 0.5 to get 54 mm for the area of the triangle.
