Given the formula A = 5h (B + b); solve for B. 2

stellarik [79]

Answer:

B = A/5h - b; You could use

B = (A - 5hb)/5h This just puts everything over a common denominator.

Step-by-step explanation:

A = 5h (B + b) Divide both sides by 5h

A/5h = B + b Subtract b from both sides.

A/5h - b = B

Solve by completing the square -x^2+8x-6=0

Svetllana [295]

-x² + 8x - 6 = 0
x = -(8) +/- √((8)² - 4(-1)(-6))
 2(-1)
x = -8 +/- √(64 - 20)
 -2
x = -8 +/- √(44)
 -2
x = -8 +/- 2√(11)
 -2
x = -8 + 2√(11) x = -8 - 2√(11)
 -2 -2
x = 4 - √(11) x = -8 + √(11)
