Answer:
your answer is a complex number making your question wrong
Step-by-step explanation:
First z²+z+20=0, just to make it a quadratic equation, so we can use the quadratric formula:
x=( -b±√b²-4ac)/2a
so to find a b and c we compare
YOUR QUESTION SHOULD BE Z² +Z-20=O.
Answer:
This is an example of explicit evidence, because explicit evidence is when it is made very clear.
Step-by-step explanation:
EXPLANATION
If receive 15% of a profit, and considering a total profit of $600, the amount is given by the expression:
Profit = 15% of 600
We must turn 15% into a decimal form by dividing it by 100 as follows:
15/100 = 0.15
So, the computed value is:
Profit = 0.15 x 600 = $90
The answer is $90.
