Answer:
14 units
Step-by-step explanation:
The angle bisector divides the sides proportionally.
BD/BA = CD/CA
(x+4)/8 = (2x+1)/12
3(x +4) = 2(2x +1) . . . . . multiply by 24 (the least common denominator)
3x +12 = 4x +2 . . . . . . . eliminate parentheses using the distributive property
12 = x +2 . . . . . . . subtract 3x
10 = x . . . . . . . . . subtract 2
Then the length of BD is ...
BD = x +4
BD = 10 +4 . . . . substitute the value of x
BD = 14
Answer/Step-by-step explanation:
Ok so there is
3, 0-4 4, 5-9 2, 10-14 1, 15-19 1, 20-24
so you can get rid of the last one saying it has more than 1 number between 20-24.
The 3rd one has to short of numbers for 0-4.
the second one has way to many 0-4's when there should be 3 of them.
therefore your answer is The firstone.
Equal them to each other and you get that x=7
Answer:
x=1.4
Step-by-step explanation:
Write the equation

Multiply both sides by x

Divide both sides by 4
