Chris is making a pennant in a shape of a triangle for his senior class photo. He wants the base of this triangle to be 4 inches. The area of the pennant must be 16 square inches

The formula for finding the area of a triangle 1/2 base * height. This time, we know the base and the area, so we have to find the height. Let's say the variable h represents height. 1/2 (4) * h = 16. 2 * h = 16. If you divide both sides of the equation by 2, you get h = 8. Therefore, the height of the triangle must be 8 inches with a base of 4 inches to get an area of 16 square inches. You can double check by doing: 1/2 (4) * 8 = 16. To check if its correct, solve it to get 2 * 8 is 16, which is accurate.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
