Answer:
Both
Claire
Andre
Neither
Step-by-step explanation:
We have to determine whether each point lies on Claire's line (blue) and whether it lies on Andre's line (black).
Point A is the intersection of both lines, hence the statement represents them both.
Point B only lies on Claire's line.
Point C is the start of Andre's line.
Point D is outside of both lines.
EXPLANATION
Let's see the facts:
The scale is---> 14 milimeters ----> 5 meters
Width = 42 milimeters
Applying the unitary method, the actual width of the pool is:

The width of the pool is 15m
Answer:
D
Step-by-step explanation:
Replace R1 with 1 and R3 with 0 you have -2(1)+0 which equals 0 and that matches matrix II. Repeat the process with the other numbers in R1 and R3 and they all come out equal therefor the answer is D.
