What is the Difference between Order of operations and Algebraic Expressions

1 answer:

7 0

The <em>Order of Operations</em> is a set of rules that tell you how to evaluate <em>Algebraic Expressions</em>.

They are different classes of object, like a knife and an apple. They cannot be compared, but one is used to make something useful of the other.

CD is the segment bisector of AB at D. If AD = 4x-1 and DB = 9x-21. what is the length of AD and AB

Artemon [7]

Answer:

AD= 15

AB=30

Step-by-step explanation:

We are given that the Point D bisect the line segment AB

Hence AD = DB

AD= 4x-1

BD=9x-21

Hence

4x-1=9x-21

adding 21 on both sides and subtracting 4x from both sides

4x-4x-1+21=9x-4x-21+21

-1+21=5x

5x=20

dividing both sides by x we get

x=4

Hence

AD = 4x-1

= 4(4)-1= 16-1=15

AD= 15

AB = 2 x AD

= 2 x 15

= 30
