                                                     Answer:

                            No, these expressions are not equivalent

                                    Step-by-step explanation:

          3e + 7 - e                                                                2e + 10 + 2e - 3

      Subtract 3e - e                                                             Add 2e + 2e    

            2e + 7                                                                       4e + 10 - 3                                  

                -                                                                         Subtract 10 - 3      

           2e + 7                                                                           4e + 7                        

        Subtract 7                                                                    Subtract 7

             2e                                                                                  4e

       Divide by 1e                                                                 Divide by 1e

               2                                                                                    4

                                                   2      ≠      4

                           No, these expressions are not equivalent

Unit 2 Lesson 2:Surface Area
seropon [69]
Part 2) <span>What is the surface area of this cube?
we know that
surface area of a cube=6*b</span>²
where b is the length side of a cube
in this problem
b=15 mm
so
surface area of a cube=6*15²----> 1350 mm²

the answer Part 2) is 1350 mm²

Part 3)  What is the surface area of this cube?
we know that
surface area of a cube=6*b²
where b is the length side of a cube
in this problem
b=11 cm
so
surface area of a cube=6*11²----> 726 cm²

the answer Part 3) is 726 cm²

part 4) <span>What is the surface area of the rectangular prism represented by the net?

surface area=2*16*6+2*16*8+2*6*8----> 544 cm</span>²

the answer Part 4) is 544 cm²

Part 5) <span>What is the surface area of the wood block?
surface area=5*5+4*[5*8]/2----> 25+80----> 105 in</span>²

the answer part 5) is 105 in²

A person invests 3000 dollars in a bank. The bank pays 6.75% interest compounded
stich3 [128]

Answer:

12.1 years

Step-by-step explanation:

We are given that

Principal amount, P=$3000

Rate of interest, r=6.75%  semi-annually

Amount, A=$6700

We know that

When r pays semi-annually

A=P(1+\frac{r}{n\times 100})^{nt}

Where n=2

Using the formula

6700=3000(1+\frac{6.75}{200})^{2t}

\frac{6700}{3000}=(1..03375)^{2t}

2.233=(1.03375)^{2t}

Taking ln on both sides we get

ln(2.233)=2t ln(1.03375)

2t=\frac{ln(2.233)}{ln(1.03375)}

t=\frac{1}{2}\times \frac{ln(2.233)}{ln(1.03375)}

t=12.1 years
