Answer:
12/7=Big/Small
Step-by-step explanation:
A side in the smaller square is 7. A side in the bigger square is 12. That means the bigger side compared to the smaller side will be 12:7. That's the definition of a scale factor.
The expressions are irrational 1/3 + √216 and √64+ √353 and the expressions √100 × √100, 13.5 + √81, √9 + √729, and 1/5 + 2.5 are rational number.
<h3>What is a rational number?</h3>
If the value of a numerical expression is terminating then they are the rational number then they are called the rational number and if the value of a numerical expression is non-terminating then they are called an irrational number.
1. √100 × √100
→ √100 × √100
→ 10 × 10 = 100
This is a rational number.
2. 13.5 + √81
→ 13.5 + √81
→ 13.5 + 9 = 22.5
This is a rational number.
3. √9 + √729
→ √9 + √729
→ 3 + 27 = 30
This is a rational number.
4. √64+ √353
→ √64 + √353
→ 8 + √353
This is an irrational number.
5. 1/3 + √216
→ 1/3 + √216
→ 1/3 + √216
This is an irrational number.
6. 1/5 + 2.5
→ 1/5 + 2.5
→ 0.2 + 2.5 = 2.7
This is a rational number.

To solve you first distribute -1/3 to 6x and 3 which would give you a new inequality of: -2x - 1 < - 14
Then to leave x on one side of the inequality you add 1 on both sides giving you: -2x < - 13
Then to get x alone you divide by -2 on both sides BUT remember that when you divide by a negative number in an inequality you flip the sign so the new one will be: x > 13/2 or x > 6.5
