I don't think you need answer for that you already did it.
Can you show the mentioned diagram?
Step-by-step explanation:
Hi mate I am new to this app
Answer:
x = -3 +/- square root(22)
Step-by-step explanation:
x = -b +/- square root(b^2 - 4ac) / 2a
ax^2 + bx + c = 0
these are both the quadratic formula but one is solved for the x and another for 0
a= 1
b= 6
c = -13
x= -6 +/- square root( 6^2 - 4(1)(13)) / 2(1)
x = -6 +/- sqrt( 36 + 52) / 2
x= -6 +/- sqrt (88) / 2
sqrt of 88 = 2 x sqrt (22)
divide 2 on each
x= -3 +/- sqrt (22)
Hi there! Your answer would be:
D, If it is an octagon, then it does not have exactly five sides.
I also know because I took this exam and it was correct.
Hope that helps!
