<span><span>∑<span>i=2</span><span>i=10</span></span>(4+2n)=</span><span>
You can do it by hand, w/o much work .
plug in n=2 into (4+2n)
then plug in n=3 into (4+2n)
then plug in n=4 into (4+2n)
etc until you get to n=10. Add them all up.
</span><span>add 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24
</span><span>144 jumps!</span>
I believe the answer is d, because i cant find a pattern where x and y are directly connected.
Product is multiplication.
The opposite of 4 is -4
3 x -4 = -12
Answer: -12
The correct answer is 3.5 pounds.
If you want to keep it in fraction form the answer would be 3 1/2
