Answer:
The first picture is a function while the second one is not.
Step-by-step explanation:
Reason - first picture passed the vertical line test, the other didn't.
29
a+b+b+c+a+c=58
2a+2b+2c=58
divide by 2
a+b+c=29
when is in quadrant II, so
Simplified :(5x+4y)(5x−4y)
=(5x+4y)(5x+−4y)
=(5x)(5x)+(5x)(−4y)+(4y)(5x)+(4y)(−4y)
=25x2−20xy+20xy−16y2
=25x2−16y2
hope this helps!
