Solve –2x2 – 16x – 44 = 0
answer please using quadtratic equation ...?
1 answer:
The quadratic formula is one way to obtain the solution of the quadratic<span> equation. It is expressed as:
x = (-b +/- </span>√b² - 4ac ) / 2a
where, for this problem, a = -2, b = -16 and c = -44.
We solve as follows:
x = (-b +/- √b² - 4ac ) / 2a
x = (-(-16) +/- √(-16)² - 4(-2)(-44) ) / 2(-2)
x = (16 +/- √256 - 352 ) / -4
x = (16 +/- √-96 ) / -4
x = -(16 +/- 4i√6 ) / 4

5 is greater than equal to 5. So f(5)=5+8=13
Step-by-step explanation:
Take it like this
27% of x = 162
27/100 * x = 162
x = 162*100/27
x=600
Therefore, 27% of 600 is 162

Answer:
Option a, 13
if you solve it, you get 13 as the answer
³√(5x-1)=4
or, 5x-1=64
or, 5x=65
or, x=13
