Answer:
Therefore the lengths of the opposite side pairs.
C) 18, 9
Step-by-step explanation:
Given:
Quadrilateral ABCD is a parallelogram
AB = 6x
DC = x + 15
AD = 9
BC = 3y
TO Find:
AB = ?
BC = ?
Solution:
Quadrilateral ABCD is a parallelogram ..........Given
∴ Both pairs of opposite sides of a Parallelogram are congruent.
∴ AB = DC and AD = BC
substituting the values we get

substituting the x' and 'y' values we get

Therefore the lengths of the opposite side pairs.
C) 18, 9
When multiplying out you get:
x2+4x-3x-12....
so you'd be adding the +4x to the -3x
x2 + x - 12
Answer:
diagonals are perpendicular......its not true
Step-by-step explanation:
hiiii
Based on the given sequence of numbers above, the best definition of it would be a geometric sequence. It is a geometric sequence because term of the sequence of numbers after the first is found by multiplying the previous one by a fixed, non-zero number, and the sequence shows a common ratio.
