Help me answer this question please​

x = 12 ft, y = 24 ft

12 ft x 24 ft

Step-by-step explanation:

12 x 24 = 288 ft²

2(12) + 24 = 48 ft fencing

x = 12 ft

y = 24 ft

Step-by-step explanation:

L = 2x + y

xy = 288 → y = 288/x

L = 2x + 288/x

dL/dx = 2 - 288/x²

0 = 2 - 288/x²

-2 = -288/x²

x² = 144

x = 12

y = 288/12 = 24

L = 2(12) + 24 = 48 ft

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
