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.

Based on the graph of a regression model:

Option: A is correct.

1( m² + 15m + 56) = (____) (m+8) 2 a² +5ab + 6b²=(a +2b (_____) pastor po

Nutka1998 [239]

Step-by-step explanation:

${m}^{2} + 15m + 56 = ( \: \: \: \: \: )(m + 8) \\ solution \\ \: \: taking \: lhs \\ = {m}^{2} + 15m + 5 \\ = {m}^{2} + (7 + 8)m + 56 \\ \: \: \: \: = {m}^{2} + 8m + 7m + 56 \: \: \\ now \: taking \: common \: factor \\ m(m + 8) + 7(m + 8) \\ (m + 7)(m + 8) \\ now \\ {m}^{2} + 15m + 56 = (m + 7)(m + 8)$

${a}^{2} + 5ab + 6 {b}^{2} = ( a + 2b)( \: \: \: \: \: \: \: \: ) \\ solution \\ taking \: \: lhs \\ = {a}^{2} + 5ab + 6 {b}^{2} \\ = {a}^{2} + ( 3+ 2)ab + 6 {b}^{2} \\ = {a}^{2} + 3ab + 2ab + 6 {b}^{2} \\now \: taking \: common \: factor \\ a(a + 3b) + 2b(a + 3) \\ (a + 2b)(a + 3) \\ now \\ {a}^{2} + 5ab + 6 {b}^{2} = ( a + 2b)( a + 3) ans$
