Answer:
b = 2
Step-by-step explanation:
3b + 2(b - 3) = 4
expand 2(b - 3): 2b - 6
3b + 2b - 6 = 4
add similar elemnets : 3b + 2b = 5b
5b - 6 = 4
add 6 to both sides
5b - 6 + 6 = 4 + 6
simplify
5b = 10
divide both sides by 5
5b/5 = 10/5
simplify
b = 2
Using the pythagorean theorem (a^2 + b^2 = c^2), this would make the equation 48^2 + b^2 = 80^2 (the hypotenuse must be plugged in as the "c" value).
Once you solve, this becomes 2304 + b^2 = 6400.
Subtract 2304 from 6400 and you get b^2 = 4096.
Take the square root of 4096 and you get b=64.
The answer is 64.
