-3 = x + x + x
-3 = 3x
-3/3 = x
x = -1
Answer:
(l-3)(l+10)
Step-by-step explanation:
Answer:
Given:
and
.
Prove: 
Since
, By the definition of perpendicular lines angles 1, 2, 3 and 4 are 90 degree. similarly
, it means angles 5, 6, 7 and 8 are 90 degree.
We can say that,
,
,
and 
From figure it is noticed that the angle 1 and 5 are corresponding angles.
If two parallel lines are intersected by a transversal, then the corresponding angles are equal.
Since corresponding angles are congruent, therefore the line must be parallel to each other.
Hence proved that
.
9 1/8
4/8+5/8=9/8=1 1/8
5+3=8
8+1 1/8=9 1/8
The answer would be the first one or 3y2, this is because it goes into each term evenly enough to simplify it.
