Answer:
4.5X10^-3
Step-by-step explanation:
Scientific notation formula= x.x times 10^x
It’s is 6 because I added it all up and all you have to do is division
Subtract 3 from both sides so that the equation becomes -2x^2 + 5x - 13 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √((5)^2 - 4(-2)(-13)) ] / ( 2(-2) )
x = [-5 ± √(25 - (104) ) ] / ( -4 )
x = [-5 ± √(-79) ] / ( -4)
Since √-79 is nonreal, the answer to this question is that there are no real solutions.
It should be 9. I hope this helps. If it's not 9 then can u please give me a list of your answers to choose from.
N is the amount of sides
sum=13 times 180 =2340
