P = 2(L + W)
P = 68.4
L = 4W + 9.7
68.4 = 2(4W + 9.7 + W)
68.4 = 2(5W + 9.7)
68.4 = 10W + 19.4
68.4 - 19.4 = 10W
49 = 10W
49/10 = W
4.9 = W <==== the width is 4.9 cm
L = 4W + 9.7
L = 4(4.9) + 9.7
L = 19.6 + 9.7
L = 29.3 <=== the length is 29.3 cm

Answer:
Answer given above
Step-by-step explanation:
a.) 6 m n^8
b.)2x^8 y^3
c. ) d^3 e
C
let y = f(x)
Then rearrange making x the subject
y = - 
x - 18 ( add 18 to both sides )
y + 18 = - x
multiply both sides by - 
- (y + 18) = x
x = - y - 27
change y to x for inverse function
(x) = - x - 27 → C
Answer:
x = 3.5
Step-by-step explanation:
To solve this you need to solve for x.
This is a two step equation so you need to first subtract 5 from itself and whatever you do to one side of the equation you have to do to the other side as well.
So 5 - 5 = 0
12 - 5 = 7
Then the equation becomes 2x = 12
Now it is a one step equation, so find the inverse operation of multiplication, which is division .
So 2 divided by 2 is 1 which also equals x by itself
7 divided by 2 equals 3.5
So x = 3.5
