176 minutes,
70x5,280= 369,600 divide by 35= 10,560 divide by 60=176
Answer:
The answer is 16x + 7
Step-by-step explanation:
First you want to add all of the like terms.
(8x + 10 + 12x + 7) - (4x+10)
20x + 17 - (4x + 10)
Now you want to subtract all of the like terms
16x + 7
Answer:
0
Step-by-step explanation:
Opposite numbers lie on opposite sides of 0 but are the same distance from 0. For example, the opposite of 3 is -3, and both those numbers are on opposite sides of 0, both 3 units from it.
The opposite of -4 is 4. Those are on opposite sides of 0 and both are 4 units from it.
Zero?
The opposite of 0 is 0 itself! The symbol -0 can be confusing if you read that as "negative zero" and expect it to be on the negative side of the number line. It's better to read that as "the opposite of zero" or, if you want to sound overly smart (but even more correct!), say "the additive inverse of 0".
This all leads up to the idea of absolute value of a number: its distance from 0.
|3| = 3
|-4| = 4
|0| = 0
3x2−21x+3=0
Step 1: Use quadratic formula with a=3, b=-21, c=3.
x=−b±√b2−4ac2a
x=−(−21)±√(−21)2−4(3)(3)2(3)
x=21±√4056
x=72+32√5 or x=72+−32√5
answer
x=72+32√5 or x=72+−32√5
