Answer:
x² - 10x + 21
Explanation:
To answer this question, we will simply multiply each term from the first bracket by each term from the second and then combine like terms to get the final expression.
This can be done as follows:
(x - 3)(x - 7)
x(x) + x(-7) -3(x) -3(-7)
x² - 7x - 3x + 21
x² - 10x + 21
Hope this helps :)
The simplified expression would be:
10-2t
Answer:
$19.60
Step-by-step explanation:
Given data
number of pages= 136 pages
number of copies = 19 copies
Hence 19 copies make a total of = 136*19
=2584 pages
hence if 500 pages cost $3.80
then 2584 pages will cost x
cross multiply
500x= 2584*3.8
500x=9819.2
Divide both sides by 500
x= 9819.2/500
x= 19.6384
x=$19.60
It will cost $19.60
Answer:
Step-by-step explanation:
Check the attached diagram... since they are parallel lines, those angles should be equal. now as per the theorem of opposite angles, (3x + 10)° should be equal to 70° .
(3x + 10)° = 70°
3x = 60°
x = 20
Substitute the x-value and see if you get the corresponding y-value. The corresponding y-value an x-value of 3 in this equation should be
Since the coordinate (3,32) does not represent that, it is a false solution
