Step-by-step explanation:

Hello.

What is the perimeter of a rectangle with width 10 inches and length 13 inches?

to find the perimeter of the rectangle we must add all its sides (4 sides)

side 1 = side 2= width=10 inches

side 3 = side 4 =lenght=13 inches

Perimeter=10+10+13+13 =46 inches

Answer

1.C 46 inches

Have a great day

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

{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
