Answer:
-8
Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.
how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.
Hi there!
One mile is equal to 5280 feet. To figure out how many miles the mountain climber climbed, all we need to do is to divide 15840 by 5280. Doing this give us 3 miles.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
The correct option is (A) No real solution.
Step-by-step explanation:
The expression provided is a quadratic equation.
The roots of a quadratic equation are:
Here,
a = 8
b = -10
c = 15
The conditions to determine real and complex roots are:
- If
then the quadratic equation has two complex roots. - If
then the quadratic equation has two real roots.
Compute the value of 
as follows:
The equation has two complex roots.
Thus, the correct option is (A).
is the same thing as
. We can rewrite this as
. Or course this is not simplified, so we can simplify to get
.
