Quadratic Formula: (-b +/- sqrt(b^2 - 4ac)) / 2a
2x^2 - 3x = 12
2x^2 - 3x - 12 = 0
a = 2
b = -3
c = -12
(--3 +/- sqrt( (-3)^2 - 4(2)(-12) )) / 2(2)
3 +/- sqrt( 9 + 96 ) / 4
3 +/- sqrt(105) / 4

Answer: 31
step by step solution: so the function is b(x)=x+41. they want to know what the function would equal when b(-10). so b(-10) means that you would plug (-10) in for x in the function so the function would now be b(x)=(-10)+41. now all you have to do is simplify the function. b(x)=31. so the function b(-10)=x+41 equals 31. hope this helped!!! have a great day.

Answer:
13
Step-by-step explanation:
4 m is 400 cm, so the number that can be cut is ...
(400 cm)/(30 cm/piece) = 13 1/2 pieces
13 pieces can be cut that are 30 cm long.
