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:
Answer:
the domain for the function y=log(x+3) is (-3,oo).
20 • 12 is 240
1/2 • 12 • 4 is 24
so 264
96 = 192 * (1/2) ;
48 = 96 *(1/ 2) ;
24 = 48 *(1/2) ;

It'a a geometric sequence with common ratio, r = 1 / 2 .
