Answer:
0,-14
Step-by-step explanation:
5(x+7)²=245
divide both sides by 5
(x+7)²=49
Taking the square root of both sides
x+7=±7
Either x+7=7
subtract 7 from both sides
x+7-7=7-7
x=0
or
x+7=-7
subtract 7 from both sides
x+7-7=-7-7
x=-14
Answer:
7A - 42
Step-by-step explanation:
7(A-6)
Distribute
7*A - 7*6
7A - 42
Answer: 1539.2nm
The space between molecule is going as X-1 function. That mean 1 molecule doesn't have space, 2 molecules have 1 space, 3 molecules have 2 space. Then 105 molecules will be will have 104 space.
Each space is 14.8nm, the total distance would be: 104 space x 14.8 nm/space= 1539.2nm
