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)
Answer:
0.6
Step-by-step explanation:
9 is the numerator and 15 is the denominator
divide 9 ÷ 15
which is 0.6
3.10
I think, Im very sorry if this is wrong!
<span>you could have 3.15=100 times 0.0315, 10 times 0.315.</span>
