Answer: C. m = -2; n = -2

have:

x² + 4x + c = (x + m)(x + n)

⇔ x² + 4x + c = x² + (m + n)x + mn

⇒ m + n = 4

mn = c

=> M=-2, n=-2 arent possible

Answer:

Rows are the steps - they go left to right and are numbered 1,2,3,... Columns are the columns - they go up and down and are lettered A,B,C,... Cells are defined by the row and column they are in.

$\bf \begin{array}{ccll} \stackrel{blueberries}{lbs}&\stackrel{jam}{cup}\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ \frac{3}{4}&\frac{1}{2}\\\\ b&1 \end{array}\implies \cfrac{\quad \frac{3}{4}\quad }{b}=\cfrac{\quad\frac{1}{2} \quad }{1}\implies \cfrac{\quad \frac{3}{4}\quad }{\frac{b}{1}}=\cfrac{\quad\frac{1}{2} \quad }{\frac{1}{1}}$

$\bf \cfrac{3}{4}\cdot \cfrac{1}{b}=\cfrac{1}{2}\cdot \cfrac{1}{1}\implies \cfrac{3}{4b}=\cfrac{1}{2}\implies 6=4b\implies \cfrac{6}{4}=b\implies \cfrac{3}{2}=b$
