Hey There!
Steps to solve (steps will be in numerical order)
1. Find the lcd of the fractions

and <span>

. The lcd for both problems will be 12.
2. To rewrite </span>

you have to multiply the numerator and denominator by three since the lcd is 12. So you're new fraction will be

. For the second fraction, since the lcd is 12 you will multiply the numerator and denominator by 4. You're new fraction will be <span>

.
3. Since the problem contains the math keyword "Further", you automatically know you have to subtract, now subtract </span>

- <span>

. First, start of by subtracting the numerators, so subtract 9-8=1 , remember the denominators will always stay the same.
In conclusion, you're answer will be </span>

, so Isabel lives <span>

farther away from Janet.
Hope This Helps :)

There are mnemonic acronyms out there for reminding you how to do this. I think of it simply as using the distributive property.
(4x-3)(x+5) = 4x(x+5) -3(x+5)
then again
= (4x² +20x) + (-3x -15)
= 4x² + (20-3)x -15 . . . . . . . combine like terms
= 4x² +17x -15
Answer:
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes.
The exemplar equation has slope
9x - 3y = 18
- 3y = -9x + 18
y = 3x - 6
m = 3
so perpendicular slope will be -1/3
D has such a slope
3y = -x + 1
y = (-1/3)x + 1/3
