Answer: y+2x=15
Step-by-step explanation:
Given
Two points A and B are (4,7) and (6,3) respectively
Using two-point form
Putting values
3. 5mn ( 2m + 6n + 1 )
4. 4a^3b^2c ( 18a^2b - 8c )
5. (X-15)(X+15)
6. -4(y-4.5)(y+4.5)
8. 2X(X-10)(X+10)
i am not sure if no. 8 is right
The first one is the second one. t(n)=20n+480
Question 4: is the first one t(n)=8n+15
awnser: 42
step by step:
1. find the racio of both
2.multiply the awnsers by 7
