Step-by-step explanation:

\star{ \text{( \: 3b + 5) + (2b + 4)}}

\text{Step \: 1 \:  :  \sf{Remove \: the \: unnecessary \: parentheses}}

\text{When \: there \: is \: a \: ( + ) \: in \: front \: of \: an \: expression \: in \: parentheses \:, there \: is \: no \: need \: to \: change \: the \: sign \: of \: each \: term \: in \: the \: expression.}

\text{That \: means, \: the \: expression \: remains \: the \: same. \: Just \: you \: have \: to \: remove \: the \: parentheses.}

\mapsto{ \sf{3b + 5 + 2b + 4}}

\text{Step \: 2 \:  : Collect \: like \: terms.}

\text{Like \: terms \: are \: those \: which \: have \: the \: same \: base.}

\mapsto{ \sf{3b + 2b + 5 + 4}}

\mapsto{ \sf{5b + 5 + 4}}

\text{ Step \: 3 \:  :  \sf{Add \: the \: numbers : 5 \: and \: 4}}

\mapsto{ \boxed {\sf{ {5b + 9}}}}

Hope I helped!

Best regards! :D

a tin mine is estimated to have tin reserves worth two million ringgit. if the monthly extraction is 5% of the value of the rese
andrew-mc [135]
Month_1 Value = Month_0 Value * 0.95

Month_2 Value = Month_1 Value * 0.95 = Moth_0 Value * 0.95*0.95 = Month_0 Value * 0.95^2

Month _n Value = Month_0 Value * (0.95)^n

After 2 years ==> n = 24

Month_24 Value = Month_0 Value * (0.95)^24 = 2,000,000 *(0.95)^24 = 583,978.05

Geometry IXL please help !
elena-s [515]

Answer:

The answer to your question is 10 in

Step-by-step explanation:

Data

Circumference = 20π in

Diameter = ?

Formula

Circumference = 2πr

Process

1.- Equal the formula to the value

                     2πr = 20π

2.- Solve for r

                        r = 20π/2π

3.- Simplification

                       r = 10/2

4.- Find the diameter

           diameter = 2r

           diameter = 2(10/2)

           diameter = 10 in
