On the drawing of ABCD and A'B'C'D', imagine drawing line segments \overline{DE} DE
and \overline{D'E'}
D
′
E
′

. Think about the areas of the rectangles this would create: Rectangle BCDE and Rectangle B’C’D’E’ . What would you expect about these areas?

b is the answer that makes most sense

step-by-step explanation:

78.59 is the mean

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
