Step-by-step explanation:
average the numbers
<span>The answer is: 2. 11
Crowbar is a Class A lever
Therefore the mechanical advantage of the crowbar can be given by either:
MA = Output distance/Input distance
OR
MA = Output force/Input force
Since, the question gives only the force, we can use the second formula.
MA = Output force/ Input Force
= 330 N / 30 N
= 11</span>
Step-by-step explanation:
(x + 8)(x - 1) = x^2 - x + 8x - 8 = x^2 + 7x - 8.
Hence a = 1, b = 7, c = -8. (Options A, D and E)
V^2 + 3v - 4 = 0 can be factored: (v+4)(v-1) = 0. Then v = -4 and v = 1.
