Answer:
No Solutions
Step-by-step explanation:
First to complete the square, it will need to look something like
a^2+2ab+b^2
so in order to get that we can see that 4n^2+8n seems to be missing a piece.
a is the square root of 4n^2 which is 2n.
8n/2n=4
4/2=2
b=2
so now add 2 to both sides of the equation so now it's
4n^2+8n+4=-13
rewrite as (2n+2)^2=-13
Now you see a negative number as the result of a exponent.
A number squared will never be negative.
Therefore the answer is
No Solutions
" of " means multiply
1/4 * 3.20/1...and just multiply....(1 * 3.20) / (4 * 1) = 3.20/4 = 0.8
or
1/4 = 0.25.....0.25(3.20) = 0.8
When You divide numbers it makes the value smaller so subtracting the exponents will make the value with that base smaller
Solution :
Given
= weight of the first side
= 6 kg = 6000 g
= distance of the first weight from the triangle.
= 3 m = 300 cm
= distance of the first weight from the triangle.
= 600 cm
Let, 
= weight of the second side
So, x = x
or 
= 3000 g
Therefore, the quantity that is used to replace the question mark in order to make the scale balance is 3000 g.
D because there are 6 sides to a dice and there are 3 options where the number is bigger than 3. Therefore 3/6 = 15/30
