Answer:
The correct answer is: C
Step-by-step explanation:
2(4x - 5) < 14x + 8
First multiply 2 by 4x and -5
8x - 10 < 14x + 8
Now find out what x is
Move 14x to the left
8x - 14x - 10 = 8
Then move 10 to the right and change it's sign to plus
8x - 14x = 8 + 10
Now combine like terms
-6x = 18
Now divide 18 by 6 to get x
x = 18/-6
x = -3
For the first one it’s b and I’m sorry but I’m not sure about the second
Y=2x2−8x+5 is standard form

3 tens= 30
7 tenths= 0.7
8 hundredths= 0.08
so 30+ 0.7+0.08= 30.78
