Answer:
4² =16
5² =25
Step-by-step explanation:
Take the perfect squares and determine if 17 is closer to the 2 square roots it is in-between. In this case, 17 is closest to 16.
3 - 
= 
- 7
First, simplify
to 
/ Your problem should look like: 3 - = - 7
Second, simplify to 
/ Your problem should look like: 3 - = - 7
Third, multiply both sides by 9 (the LCD of 9,3). / Your problem should look like: 27 - 2b = 3b - 63
Fourth, add 2b to both sides. / Your problem should look like: 27 = 3b - 63 + 2b
Fifth, simplify 3b - 63 + 2b to 5b - 63. / Your problem should look like: 27 = 5b - 63
Sixth, add 63 to both sides. / Your problem should look like: 27 + 63 = 5b
Seventh, simplify 27 + 63 to 90. / Your problem should look like: 90 = 5b
Eighth, divide both sides by 5. / Your problem should look like:
= b
Ninth, simplify to 18. / Your problem should look like: 18 = b
Tenth, switch sides. Your problem should look like: b = 18
Answer: b = 18
