A rational answer 2 + 2 = 4
The value of n in the given equation is -2.6
Step-by-step explanation:
Given,
10 = 
To find the value of n
10 = 
or, 10(3n+8) = 2 [ by cross multiplication]
or, 30n + 80 = 2
or, 30n = 2-80 [ taking the constant values in one side]
or, 30n = -78
or, n = 
or, n = -2.6
Answer:
42
Step-by-step explanation:
so you do 7 times 6 and you should get 42

Perimeter = (length+width) x 2
Let w units be the width of the rectangle.
Length of the rectangle = 2w
Perimeter:
(2w+w) x 2 = 60
(3w)2 = 60
6w = 60
w = 10
Area:
2(10) x 10
= 20 x 10
= 200 units
