The complete exercise is: "<em>
If 
is a factor of 
, where b is a constant, what is the value of b?</em>
"</h3><h3 />
You know that a factor of the given polynomial is:
Then, in order to find the value of "b", which is a constant of the polynomial, you need to follow these steps:
1. You must rewrite the polynomial as:
2. Now you must substitute 
into the polynomial:
3. Since 2 is a zero of the polynomial, you can substitute 
:
4. Finally, you must solve for the constant "b" to find its value. Then, this is:
Answer:
6 minutes
Step-by-step explanation:
Connor drives from the village to Belfast at an average speed of 40mph.
The distance covered is 20 miles.
Time = distance/ speed
Time = 20/40
Time = 0.5 hours
Time = 30 minutes.
Kelly drives from the village to Belfast at an average speed of 50mph.
Time = distance/speed
Time = 20/50
Time = 0.4 hours
Time = 24 minutes
It will take Conor 30 - 24 = 6 minutes longer than Kelly
Answer:
Radius=9
Diameter=18
Step-by-step explanation:
<span>Set up the long division.
</span>
<span>275|234</span>
2 <span>Calculate 2340 ÷ 275, which is 8 with a remainder of 140.
</span>
3 <span>Bring down 0, so that 1400 is large enough to be divided by 275.
</span>
4 <span>Calculate 1400 ÷ 275, which is 5 with a remainder of 25.
</span>
5 <span>Bring down 00, so that 2500 is large enough to be divided by 275.
</span>
6 <span>Calculate 2500 ÷ 275, which is 9 with a remainder of 25.
</span>
7 <span>Therefore, 234 divided by 275 approximately equals 0.8509
</span><span>234÷275=0.8509</span>
8 <span>Simplify
</span><span>0.8509</span>
