Answer:

D. She should find the average of 4.4 and 4.5

(4.4 + 4.5)/2 = 4.45

4.45² ≈ 19.80

4.45² is closer to 20 than 4.4² and 4.5²

next she will repeat the same process: (4.45 + 4.5)/2

romanna [79]

Answer:

Hence the expression $(m+11)(m-4)=m^2+7m-44$

Step-by-step explanation:

Explanation

The given expression is (m+11)(m-4).
We have to multiply the given expression.
Multiply the (m+11) by -4, multiply the (m+11) by m then add like terms.

$$$\frac{\begin{matrix}{} & {} & m & + & 11 \\ \times & {} & m & - & 4 \\ \end{matrix}}$

_____________

${\frac{\begin{matrix}{} & - & 4m & - & 44 \\ {{m}^2} & + & 11m & {} & {} \\ \end{matrix}}{\begin{matrix}{{m}^2} & + & 7m & - & 44 \\ \end{matrix}}}$$$
