Thus, our equation is (x - 7)^2 + (y + 2)^2 = 61

Reil [10]

Answer:

42 yards 2 feet 11 inches

Step-by-step explanation:

Freya, uses 2 yards, 1 foot, 7 inches of twine to wrap each damaged carton.

She has to repair 17 cartons.

The amount of twine needed to wrap 17 cartons

=  (2 yards 1 foot 7 inches) x 17

= 34 yards  17 feet 119 inches

Now let's convert the answer to larger units

1 yard = 36 inches

1 yard = 3 feet

Convert 119 inches to yards

119 inches = 3 yards 11 inches

17 feet = 5 yards 2 feet

Therefore, 34 yards  17 feet 119 inches = (34 + 3 + 5 ) yards 2 feet  11 inches

Answer = 42 yards 2 feet 11 inches

Thank you.
