The vertices of a quadrilateral ABCD are A(1, -3), B(4, -3), C(4, -5), and D(-1, -5). The vertices of another quadrilateral EFCD are E(1, -7), F(4, -7), C(4, -5), and D(-1, -5). Which conclusion is true about the quadrilaterals? The shape of the quadrilaterals is same but their areas are different.

The ratio of their corresponding sides is not equal.

The measures of the corresponding angles are different.

The angles and sides overlap when one quadrilateral is placed on the other.

Solve |2x - 5| = 4 if anyone could , that would be great

What value of x is in the solution set of 4x – 12 s 16 + 8x?

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
