Answer:
4th option
Step-by-step explanation:
x² - 2x - 3 = 0 ( add 3 to both sides )
x² - 2x = 3
using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 3 + 1
(x - 1)² = 4
Answer:
what do u want me to do
Step-by-step explanation:
A=2(wh+lw+lh)
l=8m
w=3m
h=2m
A=2((3m)(2m)+(8m)(3m)+(8m)(2m))
A=2((6m)+(24m)+(16m))
A=2(46m)
A=92m
Area is 92m
I think its 28.5, but you should check with someone else.
