-7 is 7 and - 9 would be 9
(3x - 2y) / (z + 4)........x = 1, y = -2, z = 3
now we start subbing
((3(1) - 2(-2)) / (3 + 4).....simplify
(3 + 4) / (3 + 4) =
7/7 =
1 <== ur answer
1) 3n+1=16-2n
- add 2n to both sides
- you should now be left with 5n+1=16
(remember the 2n gets canceled out)
- subtract 1 from both sides
- you should now be left with 5n=15
- now you divide by 5 to get n by itself
- 15 divided by 5 is 3
- n=3
2) substitute n with 3 in to the original equation
- so 3n+1=16-2n now becomes 3(5)+1=16-2(3)
- you should get 10 for both so 10=10
3) according to the segment addition postualte , XR + YR = XY.
- add 10+10 which stands for the lengths of XR and YR
Answer - XY = 20
( x - 6)² = x² - 12 x + 36
