Answer:
When you subtract a negative number from another negative number then the second negative number will become positive and the minus sign will become an addition sign.
In this case:
-13 - (-13) = 0
-13 + 13 = 0
I hope I've helped explain this a little bit better to you.
Answer:
32.5
Step-by-step explanation:
If CED is 65, then AEB is 65, therefore we can calculate that CEA is 115 because 180 - 65 = 115. Then we do 180 - 115 = 65 which is the sum of angles ACE and CAE so 65 / 2 = 32.5 which is CAE.
Hope this helped!
Answer: $2025
Step-by-step explanation:
$1.50. x 45= 67.5 items per day. 30 days is 30 x 67.5= $2025
Discriminant b^2-4ac = (-9)^2 - 4*2*9 = 9
so there are 2 roots
because of the -9x and 9 they will both be positive
