Answer:
800 sq in
Step-by-step explanation:
There are 6 sides:
2 are 20 x 8, which each have an area of 160
2 are 20 x 10, which each have an area of 200
2 are 10 x 8, which each have an area of 80
(2 x 160) + (2 x 200) + (2 x 80)
880 sq in (assuming all sides are closed and he is painting them all)
Answer:
6q-2=66.1
Step-by-step explanation:
9.5
If you add 12.4 plus 12.4 you get 24.8 then you do 43.8 minus 24.8 and you get 19 and 19 divided by 2 is 9.5
9.5+9.5+12.4+12.4=43.8

Answer:
x=1+/-4i
Step-by-step explanation:
(x+1)/3-(2x-1)/x=-1
find the common denominator,
in this case, it's going to be 3x.
(x^2+x)/3x-(6x-3)/3x=-1
(x^2+x-6x+3)/3x=-1
x^2-5x+3=-3x
x^2-5x-(-3x)+3=0
x^2-5x+3x+3=0
x^2-2x+3=0
apply the quadratic formula in order to find the roots for x.
Since ax^2+bx+c=0, in this case,
a=1, b=-2, c=3
--------------------------
x=(-b+/-sqrt(b^2-4ac))/2a
x=(2+/-sqrt(4-12))/2
x=(2+/-8i)/2
x=1+/-4i
