Answer:
18
Step-by-step explanation:
hello,
as this is a parallelogram we can write that BE = DE so
15x + 4 = 9x + 6
<=> 15x - 9x + 4 = 6
<=> 6x = 6 - 4 = 2
<=> x = 2/6 = 1/3
so BE = DE = 15/3+4=5+4=9
so BD = BE + DE = 9 + 9 = 18
the correct answer is 18
hope this helps
Answer:
13
Step-by-step explanation:
because a is the missing number. Well, 21 minus or - 8 is equal to 13.
We can treat this problem like you regularly subtract fractions. First find the common denominator, which is 15.
So:
5(x+6)/15 = 30/15 + 3(x-2)/15
(5x+6)/15 - (30/15) - (3x - 6)/15
As you already know the answer, I'm assuming you can do the rest.
Hope this helps!
