Which choice shows the coordinates of B’ if the trapezoid is reflected across the x-axis? (–7, 2) (2, –7) (7, –2) (–2, 7)

For this case we have that the original point is given by:

 B = (7, 2)

 As the point is reflected through the x axis, then we have the following transformation:

 (x, y) > (x, -y) > (x ', y')

 Applying the transformation to the original ordered pair we have:

 (7, 2) > (7, - (2)) > (7, -2)

 Point B 'is given by:

 B '= (7, -2)

i hope this was helpful please

please mark me as brainliest :)

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
