Scientific notation is usually written in powers of tens, in this case:
The answer is 2 * (2x-3).
<span>12x^2 - 10x - 12</span> = <span> 2 * (6x2 - 5x - 6)</span>
Work from there.
Hm so basically what the question is asking is
Answer:
Correct answer:
3
Step-by-step explanation:
sing the defined function, f(a) will produce the same result when substituted for x:
f(a) = a2 – 5
Setting this equal to 4, you can solve for a:
a2 – 5 = 4
a2 = 9
a = –3 or 3
