Answer:

Step-by-step explanation:
The model shows that there are 40 tiles which were divided into 4 per group. This results into 10 groups. That is:

Therefore, the expression modeled by the arrangement of the tiles is 
2x+8y
2x+8times2
2x+16
18x
Your final answer is 18x!
Answer:
kool
Step-by-step explanation:
Well,It depends on the shape of the kite and to decide that something is congruent is it has to be the exact same shape looks same everything same YW :D
You can solve this equation by rearranging the 2x to the opposite side, but since it's a positive, you must change it to a negative. If the number was negative, it would've been a positive.
y=-2x+3
-2x is the slope and 3 is the y-intercept.
Hope this helped!
