a = 3
Step-by-step explanation:
-12x³+14x²+6x = -2x(ax+1)(2x-3)

ax+1=3x+1
<em>Subtract 1 from both sides</em>
ax=3x
<em>Divide both sides by x</em>
a=3
According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.
<u>Explanation:</u>
Let the number of dogs be d and the number of cats be c
If the ratio of dogs to cats is 49:28, then the ratio of d : c would be
On reducing the fraction, we get
It is shown that the number of cats is reduced to 20.
So, let the number of dogs after sometime be x
Thus,
After cross multiplying we get:
140 = 4x
x = 35
