A rectangular yard 102 feet long and 68 feet wide has some dead grass spots. The sprinkling system waters with 6 sprinklers. They water in a circle that touches the next circle, 3 on top and 3 on bottom. The radius each sprinkler covers is 17 feet. Use = 3.14 and round your answers to one decimal place.

a. How much area does one sprinkler cover?
b. How much area do all 6 sprinklers cover?
c. What is the area of the lawn?
d. What area of the lawn is not watered?

the correct answer is 1: 2

hope this your welcome : )

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
