Answer:
11
Step-by-step explanation:
5m - 9 = 4m + 2
Subtract 4m and add 9 to both sides:
m = 11
8/11 cant be an improper fraction because the numerator is smaller than the denominator
Answer:
b = √(c^2 - a²)
Step-by-step explanation:
Start with the given c = √a^2 + b^2. Squaring both sides, we get:
c² = a² + b².
We want to iosolate b² and then b.
So: subtract a² from both sides, resulting in:
c² - a² = b²
Taking the square root of both sides, we get:
√b² = √(c² - a²)
and so:
b = √(c^2 - a²)
