Answer:
6x^2 - 3x
Step-by-step explanation:
3x (2x-1)
multiply 3x by 2x -> 6x^2
multiply 3x by -1 -> -3x
You would subtract 15 on both sides and then you would have 2x=-14 then you divide both sides by 2 and x would equal -7
Answer:
y^2/x^6
apply exponent rule:
x^-2/x^4=1/x^4-(-2)=y/y^-1 x^4 -(-2)
then you subtract 4-(-2)=6
y/x^6 y^-1
cancel out the common factor: y^-1 and you get
y^2

x^6
Answer:
23/2
Step-by-step explanation:
first turn the mixed number into a fraction:
