The coordinate plane shows the floor plan for a swimming pool. what is the area of the pool’s border? a. 50 square meters b. 65 square meters c. 80 square meters d. 100 square meters e. 125 square meters

The answer is 100 meters

Step-by-step explanation:

I used the distance formula for the length and width of the pool

The length was 10 and the width was 5

Multiplied those together to get the area which i got 50.

I did the same thing with the length and width of the pool deck.

the length was 15 and the width was 10

i multiplied those together to get the area of everything which was 150.

But now we have to subtract the area of the pool from the area of the pool deck to get the exact pool deck area without the pool in it.

This answer is right:) Hope i helped!!

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
