Answer: 25x^2 - 1^2
Explanation:
(5x+1) (5x-1)
(5x)^2 - 1^2
25x^2 - 1^2
Answer:
18 = m
Step-by-step explanation:
2=m/2-7
Add 7 to each side
2+7=m/2 - 7+7
9 = m/2
Multiply each side by 2
9*2 = m/2 * 2
18 = m
Answer:
I think "D"- 3(x + 3)
Step-by-step explanation:
as 3 years ago - x
so present age of shilpa - x +3
~~~~~~~~~~~~~
present age of sindhu - 3 (x+3)
i guess : )
Here are the answer: a) R = 3.6 and b) A = 2
Step-by-step explanation:
Given,
R is inversely proportional to A.
R ∝ ![\frac{1}{A}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BA%7D)
so, R =
-------eq 1 where k is any constant
To find the values of a) R when A = 5 and
b) Value of A when R = 9
Now,
Putting R = 12 and A = 1.5 in eq 1 we get,
12 = ![\frac{k}{1.5}](https://tex.z-dn.net/?f=%5Cfrac%7Bk%7D%7B1.5%7D)
or, k = 12×1.5 = 18
From eq 1 we get,
R =
--------- eq 2
Now,
a) Putting A= 5 in eq 2 we get,
R =
= 3.6
b) Putting R = 9 in eq 2 we get
R =
or, A =
= 2
