Answer:
Lateral : 21
surface : 39
Step-by-step explanation:
I think that this is correct. :)
Multiply entire equation by (x-2)(x+1) to get rid of the denominators That would lead to X(x+1)+(x-1)(x-2)=-1(x-2)(x+1)
Finally, using distributive property and foil, you would get x^2+x+x^2-3x+2=(-x^2+x+2).2x^2-2x+2=-x^2+x+23x^2-3x=0
3x(x-1)x=0 and x=1
Answer:
it's the fourth one
Step-by-step explanation:
Solve all the problems using exponent rules and the last one equals 632
-2(5)^2+2(5)-3
-2(25)+10-3
-50+10-3
-40-3
=-43
