Answer:
(6x+10)°=(6x+10)°[vertically opposite angle]
now,
6x+10+10x+10=180°[being cointerior angle]
16x=180-20
x=160%16
x=10°

cubic root of 8x^3= 2x^(3/3)= 2x
so 2xy^2
Answer:
One Solution
Step-by-step explanation:
Do distributive property
3k+6+3+7k=2k+4+3k
Combine like terms
10k+9=5k+4
Subtract 5k from 10k
5k+9=4
Subtract 9 from 4
5k=-5
Divide
k=-1
Hope this helped, Have a Wonderful Day!!
