Um not sure who deleted my qustion but here it is again

The area of a trapeziod is found by adding the top and bottom dimensions together, dividing that by 2, then multiplying by the height.

The top half of the window is: 16 +30 = 46/2 = 23 x 276 square inches.

The top and bottom are the same.

Total area = 276 + 276 = 552 in^2

552 in^2

Step-by-step explanation:

Area of trapezoid = 1/2(16 + 30(12)

= 1/2(46)(12)

= 276

Two trapezoids are similar

So total area = 2 x 276 = 552 in^2

{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
