x = ± i
rearrange the equation and equate to zero
2x² - 6x = - 5 ⇒ 2x² - 6x + 5 = 0
this doesn't factor with integers, hence use the quadratic formula to solve
with a = 2, b = - 6 and c = 5
x = (6 ± √(36 - 40 ) )/4
= (6 ± √(-4) ) / 4
= (6 ± 2i ) / 4
x = ± i
Answer:
Step-by-step explanation:
Answer:
because all the sides are the same length and therefore the triangles formed are the same including the angles between them
Step-by-step explanation:
if all the sides are the same then it means the angles formed are also the same so the triangles will be congruent. also line BD is cutting the shape Into two identical shapes which will definitely make the two shapes congruent and identical.
You would divide 8 by 9 to get .8 (the 8 repeats)
Rounded to the thousandths, because the 8 repeats.
Well as a high school-er this should be easy. Divide 4.27 and get an fraction of 47/11.
