Write an expression for the perimeter of the triangle shown below: A triangle is shown with side lengths labeled 0.5x plus 9, 3x, and negative 3.4x minus 25.

A: 6.9x − 16
B: 6.9x + 16
C: 0.1x − 16
D: 0.1x + 16

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
