Answer:

A number that can't be simplified to remove a square root (or cube root etc) is called surd .

There are six different types of surds, namely: Simple surds, Pure Surds, Similar Surds, Mixed Surds, Compound Surds, and Binomial Surds

  • When we can't simplify a root under variable further or we can't remove the root sign that is called surd.It may be a square root or cube root or n th root .They are especially called irrational numbers.

Ex:-

\\ \rm\longmapsto \sqrt{9}=3Hence its not a surd.

but

.

\\ \rm\longmapsto \sqrt{3},\sqrt{7}Are surds.

There are six types of surds such as :

  1. Simple surds
  2. Pure Surds
  3. Similar Surds
  4. Mixed Surds
  5. Compound Surds
  6. Binomial Surds.

A boy purchased​ (bought) a​ party-length sandwich 56 in. long. He wants to cut it into three pieces so that the middle piece is
erik [133]

The shortest piece is 14 inches, middle piece is 19 inches and longest piece is 23 inches long.

Step-by-step explanation:

Let,

x be the shortest piece.

Therefore,

Middle piece = x+5

As shortest piece is 9 in shorter than longer piece;

Shortest piece = longest piece - 9

x = longest piece - 9

longest piece = x+9

Length of sandwich = 56 in

According to given statement;

Shortest piece + middle piece + longest piece = 56

x+(x+5)+(x+9)=56\\x+x+5+x+9=56\\3x+14=56\\3x=56-14\\3x=42

Dividing both sides by 3;

\frac{3x}{3}=\frac{42}{3}\\x=14

Shortest piece = 14 in

Middle piece = 14+5 = 19 in

Longest piece = 14+9 = 23 in

The shortest piece is 14 inches, middle piece is 19 inches and longest piece is 23 inches long.
