At x=-3:
2x^2+ x
= 2(-3)^2+ (-3)
= 2*9 -3
= 18 -3
= 15
The value of 2x^2+ x is 15 if x=-3~
Answer:
yes I sont now how tu understand
If angles are the same, then their opposite edges also the same. So 2x-6 = x
If you solve it you will find x=6
These two have different denominators, so you find the least common multiple. This problem goes to be 2/8+5/8, which equals 7/8。
