#4. Find the value of x and use it to find the length of CE, BD, and BE Find BD.

almond37 [142]

Answer:

x = 8
12 = BD
23 = BE
13 = CE

Step-by-step explanation:

We know that:

BD = 2x - 4
DE = 2x - 3 - 2
BE = 3x - 1
CE = 2x - 3

Solution:

(2x - 4) + (2x - 3 - 2) = 3x - 1
=> 2x - 4 + 2x - 3 - 2 = 3x - 1
=> 4x - 9 = 3x - 1
=> 4x - 3x = 9 - 1
=> x = 8
=> 2x - 4 = BD
=> 2(8) - 4 = BD
=> 16 - 4 = BD
=> 12 = BD
=> 3x - 1 = BE
=> 3(8) - 1 = BE
=> 24 - 1 = BE
=> 23 = BE
=> 2x - 3 = CE
=> 2(8) - 3 = CE
=> 16 - 3 = CE
=> 13 = CE

Hence, the answers are:

x = 8
12 = BD
23 = BE
13 = CE

A parallelogram has sides of length 7.7 millimeters and 17.2 millimeters. What is the perimeter?

Arlecino [84]

Solutions

We know that a rectangle has four sides and the perimeter of a rectangle is the distance around the outside of the rectangle.The opposite sides of a rectangle are congruent To find the perimeter you have to use the formula 2 × (Side A + Side B).

We have the side lengths 7.7 mm and 17.2 mm.

Solve

2 × (Side A + Side B)
2 × ( Side A (7.7) + Side B (17.2) )
= (7.7 x 2) + (17.2 x 2)
= 49.6

The perimeter is 49.6 mm².
