Form the intersection for the following sets. R = {10, 15, 20}
S = {20, 25}
RnS =
{ }
{10, 15, 25}
{20}
{10,15, 20, 25}

RnS=20

Step-by-step explanation:

because 20 can be found in R and at the same time can be found in S

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

i would pic false cause it goes down towards negative
