Answer:

Step-by-step explanation:
Given the following question:

In order to simplify the expression given we can only cancel the common factor which is four.




Cannot be simplified further due to it not having any more common factors. Your answer is "3x + 7 / x + 2."
Hope this helps.

Answer:
The triangles SYX and SYZ are congrient so by CPCTC
,
and
.
Step-by-step explanation:
Given information: YS is the perpendicular bisector of XYZ.
In triangle YXS and triangle YSZ,
(YS is the perpendicular bisector of XYZ)
(Common side, Reflexive property)
(YS is the perpendicular bisector of XYZ)
By ASA postulate,

The corresponding parts of congruent triangles are congruent. so,



R-9s=2 add 9s to both sides
r=2+9s making 3r-3s=-10 become:
3(2+9s)-3s=-10 perform indicated multiplication on left side
6+27s-3s=-10 combine like terms on left side
6+24s=-10 subtract 6 from both sides
24s=-16 divide both sides by 24
s=-16/24
s=-2/3, making r-9s=2 become:
r-9(-2/3)=2 perform indicated multiplication on left side
r+6=2 subtract 6 from both sides
r=-4
So s= -2/3 and r= -4
