Step-by-step explanation:
3x - 9 +2x + 9 = 2x - 2
5x = 2x - 2
5x - 2x = - 2
3x = - 2
x= - 2/ 3
The denominator( s ) we are given are
, and . The first thing we want to do is factor the expressions, to make this easier -

This expression is a perfect square, as ( x )^2 = x^2, ( 2 )^2 = 4, 2 * ( x ) * ( 2 ) = 4x. Thus, the simplified expression should be the following -

The other expression is, on the other hand, not a perfect square so we must break this expression into groups and attempt factorization -

Combining ( x + 2 )^2 and ( x + 2 )( x + 3 ), the expression that contains factors of each is ( x + 2 )^2 * ( x + 3 ), or in other words the LCM.

Answer:
Option: A is the correct answer.
The number of weeds is decreasing by a multiplicative rate.
Step-by-step explanation:
Clear;y from the scatter plot we could observe that with the increasing value of one variable the other variable is decreasing.
Hence, The number of weeds is decreasing.
Also as we could see that the line of best fit is a curve and not a line Hence, the number of weeds are not decreasing by a additive rate ( since the rate or a slope of a line is constant) it is decreasing by a multiplicative rate.
<em>Based on the graph of a regression model:</em>
<em>Option: A is correct.</em>
