Given:
The width of a rectangle is x centimeters and its length is (x+ 2) cm.
To find:
The expression for the perimeter of the rectangle.
Solution:
We know that, perimeter of a rectangle is

We have,
Width = x cm
Length = (x+2) cm
Putting these values in the above formula, we get




Therefore, the required expression for the perimeter of the rectangle is (4x+4) cm.
Answer:
i think its 17 sos if its wrong
Step-by-step explanation:
GP = 1/2 , 1/4 , 1/8 , 1/16
1st) the common ratio is (1/4 : 1/2 ) = 1/2, so r =1/2
2nd) the sum of a GP is:
S= a(1-rⁿ)/(1-r)
S=(1/2).[1-(1/2)⁴]/(1-1/2) = 15/16
Answer:
m-9 = 3 is the required expression
