Step-by-step explanation: If you have 4 apples and then Manny takes away 4 of you apples you have 0
5x - 2y + 1z = 8 ⇒ 5x - 2y + 1z = 8
-9x + 2y + 2z = 5 ⇒ -9x + 2y + 2z = 5
-9x - 2y - 5z = 4 -4x + 3z = 13
5x - 2y + 1z = 8
-9x + 2y + 2z = 5 ⇒ -9x + 2y + 2z = 5
-9z - 2y - 5z = 4 ⇒ -9x - 2y - 5z = 4
-18x - 3z = 9
-4x + 3z = 13
-18x - 3z = 9
-22x = 22
-22 -22
x = -1
-18x - 3z = 9
-18(-1) - 3z = 9
18 - 3z = 9
- 18 - 18
-3z = -9
-3 -3
z = 3
5x - 2y + z = 8
5(-1) - 2y + 3 = 8
-5 - 2y + 3 = 8
-2y - 5 + 3 = 8
-2y - 2 = 8
+ 2 + 2
-2y = 10
-2 -2
y = -5
(x, y, z) = (-1, -5, 3)
25, is it absolute value, the answer to this expression in this case

Answer:
this should be 132 units i hope this helps! :)
Step-by-step explanation:
so these figures are similar
we are given 3 side measurements on one, and 3 on the other
we know that side BA is 10 units, and that SR which is the same side, is 14 units
we can conclude that they added 4 units to this side
so with the other side lengths that we are given we can figure out what the length of the perimeter of RSTUV is
10 + 4 = 14
15 + 4 = 19
28 - 4 = 24
42 - 4 = 38
25 + 4 = 29
42 TU
28 UV
19 VR
14 SR
29 ST
add all the side together to get 132 units
