Which equations? I think you forgot to post a picture.
Answer:
x = - 3
Step-by-step explanation:
4 - (x + 1) = 6
- (x + 1) = 6 - 4
-x - 1 = 6 - 4
-x - 1 = 2
- x = 2 + 1
- x = 3
x = - 3
If you need the process explained more in depth just let us know
Understanding perpendicular and parallel lines are extremely important, especially in the engineering field when building infrastructures or houses because they need to calculate how they will keep a building stable. For example, bridges we see have a lot of perpendicular and parallel lines, that's because without those the bridge can't hold itself up, it needs support from the metals that are parallel and perpendicular.
hope this helps!!
Answer: 18
Step-by-step explanation:
The least common denominator of 
and 
is going to be a multiple of 9 and 6. Let us list them out:
9: 9, <u>18</u>, 27, 36, 45, 54, 63, 72, 81, 90
6: 6, 12, <u>18</u>, 24, 30, 36, 42, 28, 54, 60
You can see I bolded and underlined 18. Why? This is the first common multiple of 9 and 6 so it is our least common denominator (LCD).
