30 + 2w = 2 • (w - 15)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation
Solve : w-15 = 0
Add 15 to both sides of the equation :
w = 15
The answer is c. I had to do this one on a test and the teacher put this one on the bored

Answer:
8.06
Step-by-step explanation:
A² + B²= C²
4² + B² = 9²
16 + B² = 81
B² = 81 - 16
B² = 65
B = 
B = 8.06225775
Rounded = 8.06
