Answer:

7a-2

Step-by-step explanation:

to represent the perimeter of 2a-3 and 2a and 3a+1

The given sides are 2a-3 and 2a and 3a+1

To find out the perimeter we add all the sides

$Perimeter = 2a-3 +2a+3a+1$

Now combine like terms to add the terms

2a+2a+3a becomes 7a

-3+1 is -2

Now the perimeter becomes

$Perimeter = 2a-3 +2a+3a+1$

$Perimeter = 7a-2$

An expression to represents the perimeter is 7a-2

Adding all of the expressions together, (2a-3+2a+3a+1), would equal 7a-2. I hope my answer helps!

Exercise

svp [43]

By addition of all the exercise and substracting it from 1 hourJavier runs on treadmill on Monday is 0.40 hour.

Now According to the question javier completed 3 repetitions of each exercise so by multiplication time taken by javier to complete each exercise is as follow;

Squats = 0.8*3= 0.24 hour

Crunches = 0.03*3 = 0.09 hour

Lunges = 0.04*3 = 0.12 hour

curls = 0.05*3 = 0.15 hour

we can calculate total time taken to complete all exercise by Addition is,

0.24 + 0.09 + 0.12 + 0.15

0.60 hour

time taken on treadmill by javier;

1 hour - 0.60 hour

0.40 hour

Choose one of the factors of 6x^3 + 6

ivanzaharov [21]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$6x^3+6$

Now, by factorising , we get

$6x^3+6\\=6(x^3+1)$

Now, we use the formula i.e.

$a^3+b^3=(a+b)(a^2-ab+b^2)$

By using this, we get ,

$6(x^3+1)\\=6(x+1)(x^2-x+1)$

So,

$(x+1) \text{ is the factor of }6x^3+6.$

How is a calculation of net worth different from a day-to-day or month-to-month tallying of expenses?

alina1380 [7]

The difference in tallying of expenses from a day to day and month to month is the consistency. in a day to day basis it is consistent the time for a day is 24 hrs it will not change, so you will really know why the expenses goes up or down/ unlike for a month to month it is inconsistent,, some months have 30, 31 or 28 days in a month.
