Answer:
x = 4 or x = -3
Step-by-step explanation:

Take square both the sides,

x² - x - 12 = 0
x² - 4x + 3x - 3*4 =0
x*(x - 4) + 3*(x - 4)= 0
(x- 4 )(x+3) =0
x -4 =0 or x + 3 = 0
x = 4 or x = -3
Answer:
It would be 120
Step-by-step explanation:
You need to multiply 13.4 by 5,880,000,000,000.
First, we change both numbers into scientific notation.
13.4 = 1.34 * 10^1
5,880,000,000,000 = 5.88 * 10^12
Now we multiply the numbers written in scientific notation.
1.34 * 10^1 * 5.88 * 10^12 =
= 7.8792 * 10^13
The answer is choice A.
