PLEASE ANSWER ASAP Using the following equation, find the center and radius:

x2 + 2x + y2 + 4y = 20

The center is located at (1, 2), and the radius is 25.
The center is located at (−1, 2), and the radius is 25.
The center is located at (−1, −2), and the radius is 5.
The center is located at (1, 2), and the radius is 5.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
