Answer:

Step-by-step explanation:
A quadratic equation in one variable given by the general expression:

Where:

The roots of this equation can be found using the quadratic formula, which is given by:

So:

As you can see, in this case:

Using the quadratic formula:

Therefore, the answer is:

Answer:
1a = 8 cu. in.
1b = 48 cu. yd.
1c = 15 cu. ft.
2a. 36 cu. yd.
2b = 126 cu. ft.
2c = 90 cu. ft.
3a = 112 cu. in.
3b = 60 cu. yd.
3c = 189 cu. ft.
Step-by-step explanation:

Step-by-step explanation:
15.26 rad * ( 180 degree /
rad ) ;
= [ (15.26 * 180) /
] degrees ;
= [ ( 2746.8 ) /
] degrees.
= [ ( 2746.8) / 3.14) ] degrees ;
= 874.3336 degrees;
→ round to: " 874.33 degrees ."
