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

the image of (6, 9) under a dilation is (4, 6). the scale factor is

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
