Answer:
16 units
Step-by-step explanation:
RST was dilated by a scale factor of 1/2. This means R'S'T' has sides that are 1/2 the length of the sides of RST.
Since the legs of R'S'T' are 8 units, this gives us the equation
8 = 1/2x
Divide both sides by 1/2:
8÷1/2 = x
8 × 2/1 = x
16 = x
Each leg in RST is 16 units.

An example of a threat to scientific integrity is creating or distorting scientific findings to take credit on an experiment. This could also be a threat to humanity since we rely on the new breakthroughs of science for our reference to further research and calculations. If these data are not accurate or true at all, then where will we base our further study?
Let U = {1, 2, 3, 4, 5, 6, 7), A = {2, 4, 6, 7), and B = {1, 4, 7}. Find the set (A U B)'.

Step-by-step explanation:
(A U B) = {1,2, 4, 6, 7}
(A U B)'= U- (A U B) = { 3,5}<------- Answer
Answer:
You plug in -2 into where it says x, then you solve.
