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!

The length around the outside of semicircle O from point L through point M to point N is 14 centimeters. The perimeter of semici
Luden [163]
The area would be 83.67 cm.

A semicircle is half of a circle.  The perimeter of the semicircle would be half of the perimeter (circumference) of the entire circle.  The formula for circumference is:

C=πd

Using our information, we have  

22.92 = 0.5(3.14)d
22.92 = 1.57d

Divide both sides by 1.57:

22.92/1.57 = 1.57d/1.57
14.6≈d

Since the diameter is 14.6, the radius is 14.6/2 = 7.3.

We use the radius for the area of the semicircle:

A=0.5πr²
=0.5(3.14)(7.3)²
=83.67

How Can associative Property be used to mentally find 48+82?
Marizza181 [45]
Associative property of addition represents this equation:
a + b = b + a
So, how would it be helpful with this given equation?
=> 48 + 82
=> Let's start with the ones place value.
(2 + 8) = 10, bring down 0, carry 1 then ( 4 + 8) = 12 + 1 = 13
So the answer is 130.
If we are going to do it vice versa, still expect that the same answer will occur.
