Answer:
The answer is 70
Step-by-step explanation:
Answer: 48 units
Given,
ABCD is a parallelogram
The diagonals bisect at E
Line segment AE = t + 2
Line segment CE = 3t – 14
Line segment DE = 2t + 8
Line segment DB is unknown
Since ABCD is a Parallelogram, Midpoint AC = Midpoint DB
The midpoint is E
Therefore
AE = CE … (Equation I)
DE = BE … (Equation II)
DB = DE + BE
Since DE = BE (Equation II),
DB = 2DE = 2BE
Given, DE = 2t + 8
DB = 2(2t + 8)
DB = 4t + 16 … (Equation III)
To solve for the value of ‘t’
AE = CE … (Equation I)
Line segment AE = t + 2
Line segment CE = 3t – 14
Therefore, t + 2 = 3t – 14
Subtract t from both sides of the equation
3t – 14 – t = t + 2 – t
2t – 14 = 2
Add 14 to both sides of the equation
2t – 14 + 14 = 2 + 14
2t = 16
t = 8
Substitute 8 for t in Equation III to solve for the length of line segment DB
DB = 4t + 16 … (Equation III)
DB = (4*8) + 16
DB = 32 + 16
DB = 48
Therefore, the length of line segment DB is 48 units
Here is the graph. A way you could graph this is notice how this equation is in point-slope form.
A line that passes through (x1, y1) and has slope m
y - y1 = m(x - x1)
Using the equation, you could find out that the line has a slope of -2/3 and passes through the point (-9,5).
Have an awesome day!
A is not part of the problem, and it's what makes the condition false. B is the opposite of the statement being proved. C is the condition, not the hypothesis. However, D is the statement we are trying to prove, or the hypothesis.
What magic trick??
Are you gonna do a magic??
