Quadrilateral ABCD is a parallelogram if both pairs of opposite sides are congruent. Show that quadrilateral ABCD is a parallelo
gram by finding the lengths of the opposite side pairs. What is the length of BC?
2 answers:
BC is the length of AD because they are parallel. Have a nice day
Answer:
BC is 8 units length
Step-by-step explanation:
The following information is missing in the question:
AB= 4x
CD= 2y
AD= y + 4
BC= 2y
Given that ABCD is a parallelogram, then the opposite sides are congruent. That means:
AB = CD -> 4x = 2y (eq. 1)
BC = AD -> 2y = y + 4 (eq. 2)
Solving equation 2:
2y = y + 4
2y - y = 4
y = 4
Solving equation 1:
4x = 2*4
x = 8/4
x = 2
This means that
BC = 2*4 = 8 units length
CD = 2*4 = 8 units length
AB= 4*2 = 8 units length
AD= 4 + 4 = 8 units length

<u>Answer</u>
C. 39.71
<u>Explanation</u>
33 = p - 6.71
The first step is to make the like terms to be on the same side.
Add 6.71 on both sides of the eqution
33 + 6.71 = p - 6.71 + 6.71
39.71 = p
∴ p = 39.71
So the first one, 1.2 >11/5. and the second one 1/3> 1/2
Answer:
-4 = ?
Step-by-step explanation:
<u>Step 1: Substitute -1 for x</u>
7x^3 + 5x^2 - 2 = ?
7(-1)^3 + 5(-1)^2 - 2 = ?
7(-1) + 5(1) - 2 = ?
-7 + 5 - 2 = ?
-4 = ?
Answer: -4 = ?
