Answer:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=10·4+6·4+8·4+1
2·﹣104+2·(10·6)2+2·(10·8)2﹣64+2·(6·8)2﹣84=144

Step-by-step ex planation:
You can graph by using the slope and y-intercept.
Slope: 2/3
Y-intercept: -2
Answer is (D). -6-7x. Or to play with it a lil bit -7x-6. The numbers and coefficients and signs are all correct doesn’t matter how you form them unless “they” disagree with it
