Answer:
b : a = 1 : 4
Step-by-step explanation:
<em>
=
</em>
<em>3 ( a + b) = 5 ( a - b)</em>
<em>3 a + 3 b = 5 a - 5 b</em>
<em>5 b + 3 b = 5 a - 3 a</em>
<em>8 b = 2 a</em>
<em>
=
</em>
b : a = 1 : 4
Answer: try 3(2p+1) factor form
No, there is not common ratio...
0.972 (common ratio is 0.3...10.8*.3*.3)
you can use the geometric mean to find this center value easily...
(18*8)^(1/2)=12
11x = 44
X=4
44 + 7 = 51
5x = 20
31 + 20 =51
51 = 51
