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}}}$$$

The circumference (C) C of a circle is 18 18 centimeters. Which formula can you use to find the radius (r) r if you know that C=

Serga [27]

C = 2πr

r = radius

c = circumference = 18

Plug in the corresponding numbers with variables.

18 = 2πr

Isolate the r. Divide 2 and π from both sides

(18)/2π = (2πr)/2π

9/π = r

C/π = r is your formula to finding r.
