"of" means multiply and "is" means equal
1. 
x = 14
x = 14(3) <em>multiply both sides by 3 to isolate "x"</em>
x = 42
2. 
x = 14
x = 14(5) <em>multiply both sides by 5 to isolate "x"</em>
x = 70
3. 
x = 14
2x = 14(5) <em>multiply both sides by 5 </em>
2x = 70
x = 35 <em>divide both sides by 2 to isolate "x"</em>
4. 
x = 14
7x = 14(8) <em>multiply both sides by 8 </em>
7x = 112
x = 16 <em>divide both sides by 7 to isolate "x"</em>
Answers: 42, 70, 35, 16
Answer:
2 - 
Step-by-step explanation:
Using the addition formula for tangent
tan(A - B) = 
and the exact values
tan45° = 1 , tan60° = , then
tan15° = tan(60 - 45)°
tan(60 - 45)°
= 
= 
Rationalise the denominator by multiplying numerator/ denominator by the conjugate of the denominator.
The conjugate of 1 + is 1 -
= 
← expand numerator/denominator using FOIL
