#3.) 48 pieces of ribbon
#3.) this week they cost $112
X=y+z
subtract y from both sides
-y+x=z that is your answer
It is A hope this helps :)
This is x^3+x^2+1=-x in math terms, where x is the number. So x^3+x^2+x+1=0. We can write this: x^2(x+1)+(x+1)=(x^2+1)(x+1)=0. The only real solution is x+1=0, so x=-1.
Hopefully that makes sense
a^2 evaluates to
a^2+a evaluates to
Multiply the exponent of a by 2giving
The answer is
a^2 evaluates to
+ =
The answer is
a^2+a+a^2 evaluates to
