What is the value of B if the value of A+ is 15? My teacher gave me a B grade out of 15 points so how much did I get??

B range - 12.45 - 12.9

Step-by-step explanation:

A b is 83-86 in a normal school.

83% is 12.45

86% is 12.9

something in between those two.

Some schools use differnet grading methods so if you put your percentages i can calculate them for you as well

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
