1. Use Difference of squares: a^2-b^2=(a+b)(a-b)
(x+k)(x-k)=0
2. Solve for x and k
x=+-k
k=+-x
The answer to the question is d
Answer:
X = 32 meters.
Step-by-step explanation:
- Let the unknown distance be X.
<u>Given the following data;</u>
- Distance = 8 meters per hour
- Time = 4 hours
To find how many meters he would cover in four hours;
1 hour = 8 meters
4 hours = X meters
Cross-multiplying, we have;
X = 8 * 4
<em>X = 32 meters.</em>
Firstly, you know you have 27 (35/100)
Make this an improper fraction. 2735/100
Simplify this as much as you can. 547/20
Find how many times 20 will go into 540, and use the 7/20 as the fraction part of your mixed number.
Now, make as many whole as you can and states your remaining. 27 7/20
