Step-by-step explanation:

from difference of two squares:

therefore:

factorise out ¾ :

Answer:
5
Step-by-step explanation:
Use the distance formula 
insert the numbers into the formula 
2+1=3 and 0-4=-4
=9 and
= 1
9+16=25
the square root of 25 is 5
Answer:
$1.05
Step-by-step explanation:
The amount of money they should pay is 4.15+6.35+2*1.1+1.25 = $13.95

Answer:
Step-by-step explanation:
1 semester = 4474
8 semester = 8* 4474 35792
1 semester books = 389
8 semester books = 8* 389 <u> 3112 </u>
Total 38904
If he is going to pay this off in 10 years, he would have to have an increase of 3890.40 (after all income taxes) to pay it off. Fewer years would mean dividing by the number of years.
So for 8 years for example, he would need 4863 every year.
That number is obtained by dividing 38904 / 8
In 6 years he would need
38904/6 = 6484 extra dollars.
Answer:
<h2>10</h2>
Step-by-step explanation:
Let us give a proper illustration in the number line
let H be Abby's house
and S be the school
let W be her mother's work.
kindly find attached a rough sketch of the number line for your reference
Question:<em> What value represents the difference in position between Abby's house and her mother's store?</em>
basically, the distance between two points on a number line is the difference between the points.
So the value that represents the position between Abby's house and her mother's store is the distance between the two points.
= 4-(-6)
=4+6
=10
