<span>(x/y)+(3/y)=(x+3)/y
the answer is
the numerator for the following rational expression</span> is x+3
The first square has side lengths of 4 units(because the square root of 16 is 4). The second square has side lengths of 8 units. The third square has side lengths of 12 units. As you can tell, the side lengths increase by 4. So the fourth square will have side lengths of 16 units, and the fifth square will have side lengths of 20 units. The question wants the perimeter, so the answer is 20*4(sum of 4 sides of equal lengths) which is 80 units.
Answer:
(x+6)
Step-by-step explanation:
because you have ( x+6) on bottom of the first equation and on the top on the second equation
Answer: 11.4%
Step-by-step explanation:
100% of your life is 57 years
?% will be 6.5 years?
this is a simple ratio problem:
57 --> 100%
6.5 ---> (6.5 x 100)/57 ≅ 11.4%
You have known the person for about 11.4% of your life.
Answer:
x = 3.162
Step-by-step explanation:
Your first step is to get x by itself by subtracting 3 from both sides.
3-
= -7
- = -10
Now multiply by both sidex by -1 to make x positive.
= 10
now take the square root of both sides.
= 
x =
x = 3.162
