B) 18 by 5
C) 15 by 4
D) 16 by 3
help

Answers

Answer 1

Answer:

Step-by-step explanation:

Width =  w units

Length = ( w + 13 ) units

Perimeter of rectangle = 38 units

2* (length + width) = 38

2*(w +13 + w )= 38            {Use distributive property: a*(b+c)=(a*b) +(a*c)

2* ( 2w + 13)   = 38  

2*2w + 2*13   = 38

     4w + 26   = 38              {Subtract 26 from both sides}

              4w   = 38 - 26

              4w =  12       {Divide both sides by 4}

                w = 12/4

w = 3 units

Length = 3 + 13 = 16 units

Answer 2
the answer is c because if you don't know the answer and you want to guess the best answer would be c always for guessing

Find the interest earned from an investment of $14000 for 4 years at an interest rate of 6.85% compounded continuously. Round to the nearest cent.

Answers

Answer:

$4242

Step-by-step explanation:

Given data

Principal=  $14000

TIme = 4 years

Rate= 6.85%

Let us find the final amount A

A=P(1+r)^t

substitute

A=14000(1+0.0685)^4

A=14000(1.0685)^4

A=14000*1.303

A=$18242

Hence the interest is

Interest= Final amount-Principal

=18242-14000

=$4242

7x - 2(3x - 5) = 26 ​

Answers

Answer:

x=16

Step-by-step explanation:

7x−2(3x−5)=26

Use the distributive property to multiply −2 by 3x−5.

7x−6x+10=26

Combine 7x and −6x to get x.

x+10=26

Subtract 10 from both sides.

x=26−10

Subtract 10 from 26 to get 16.

x=16

Graph if needed:

Answer:

x = 16

Step-by-step explanation:

7x - 2(3x - 5) = 26 ​

7x - 6x + 10 = 26

7x - 6x + 10 - 10 = 26 - 10

x = 26 - 10

x = 16
