Four parallel lines are drawn in a rectangular sign. the sign is painted using two colors in an alternating pattern, as shown. which statements must be true about the two congruent, shaded figures? check all that apply. a.) the figures are rectangles because they are formed inside a rectangle. b.) the figures are rhombi because they are formed by four congruent line segments. c.) the figures are trapezoids because each has exactly one pair of parallel sides. d.) the figures are parallelograms because their opposite sides are parallel. e.) the figures are quadrilaterals because each has four sides. the answer is not a, d, & e, for some reason.

Look at the shaded areas and then read A. A rectangle has 2 sets of parallel lines (as these two figures do) and 1 right angle somewhere.  These two shaded regions do not have 1 right angle.

B: B is not correct because the shaded figures have 2 sets of 2 equal lines. A rhombus has 4 equal lines.

C: Not true either. The lines have 2 sets of parallel lines. Trapezoids have only 1 set.

D.  D is true

E.  E is true.

Perhaps you are not supposed to consider what the figures look like. I don't know how to answer the question. You likely got the same answers I did. Any chance you copied the wrong diagram?

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
