Answer:
We can describe FOIL using the distributive property of multiplication. For real numbers x, y, and z the distributive property of multiplication states that
Now let 
, where v and w are real numbers.
Then 
Here, we can again use the distributive property of multiplication to get
Hence, it follows that
This is the method of FOIL (first: xv, outside: xw, inside: yv, last: yw)
For example, 
18. 105=2x-11 so 105+105=210 and all four angels equal 360 so 360-210=150 so 150/2=75
19. 6x+19+x =180
X=23
So AEB:75 BEC:123 CED:75 AED:23
Please give brainliest it took for ever
Scale for y - 1:1
Scale for x - 1:10
Reason- so that i can plot the points on the graph without any modification to the given one.
Now plot the points on the graph using the scale. I cant obviously do that here.
the answer in the attached figure
