Answer:
1
= -----------
6(x + 7)
Step-by-step explanation:
3x - 21 x^2 - 49
----------- ÷ -------------
18x - 18 x - 1
3x - 21 x - 1
----------- × -------------
18x - 18 x^2 - 49
Factor the top left:
3x - 21 = 3(x - 7)
Factor the bottom left:
18x - 18 = 18(x - 1)
Factor the new bottom right:
x^2 - 49 = (x + 7)(x - 7)
Multiply and simplify the faction:
3(x - 7) x - 1
----------- × -----------------
18(x - 1) (x + 7)(x - 7)
1
= -------------
6(x + 7)
Answer:

Step-by-step explanation:
We can break the problem into three parts,
tan45 = sin(45)/cos(45)=


Then,
Therefore, the solution is sqrt(3)/3
24=7/8g
divided by 7/8 divided by 7/8
24*8/7=g
192/7=g
27 3/7=g
The answer is D. 27 3/7
the amnwer is 1.6. all you do is 8 dived by 5
