1) b^2 - 4ac = ( -2 )^2 - 4×( 0.5 ) × 2 = 4 - 4 = 0;
2) b^2 - 4ac =( -5)^2 - 4×2×20 = 25 - 160 = - 135 ;
Answer:
$1,263.74
Step-by-step explanation:
Take 15% of 8,425
The length would be 10yds and the width would be 5yds as they multiply together to give 50yds squared as an area and 10 is twice the amount of 5. So that means the perimeter would be 10+10+5+5 which = 30yds.
It's 12. I mean think of all the numbers, 6 works for 3 but not 4, 8 works for 4 but not 3 and 10 works for neither.
The answer would be 6.4% because you have to do 16% of 40 and it will give you 6.4 and as a percent it is 640%
