To simplify the expression we proceed as follows:
<span>d^2+4d+3/d^2-7d-8 + d^2-2d-8/d^2+5d+6
putting like terms together we have:
(d^2+d^2)+(4d-7d-2d+5d)+(3/d^2-8/d^2)+(-8+6)
=2d^2+0d-5/d^2-2
=2d</span>²-5/d²-2
Answer: 2d²-5/d²-2
Answer: 13.6
Step-by-step explanation:
subtract the lowest number from the highest number to find the range. in this case, the data range is 25.6−12=13.6
5/10 = 1/2
8/18 = 4/9
1/2 > 4/9
They're not proportional.
