Answer:
it dropped -141 in 60 seconds so 141/60 = 2.35 ft per second
Step-by-step explanation:
A² = 9
substitute A = - 3 into A² , that is
A² = (- 3)² = - 3 × - 3 = 9
5(3x+4)=23
15x+20=23
15x=23-20
15x=3
x=3/15
x=1/5=0.2
x2 - 4x - 12 = 0
x2 - 6x + 2x - 12= 0
x(x - 6) + 2(x - 6) = 0
x + 2 = 0
x = - 2
x - 6 = 0
x = 6
