The perimeter of the rectangle abcd is
74 units. find the length of side ab if:
dc (top) = 4z-1
cb (right side) = 3z+3

length=19

Step-by-step explanation:

top is length and right side is breadth.

perimeter = 2(l+b)

74 = 2[(4z-1)+(3z+3)]

74/2 = 4z-1+3z+3

37 = 7z+2

7z= 37-2

7z = 35

z = 35/7

z = 5

.: length = top = 4z - 1= 4(5) - 1

= 20-1=19

.: length= 19

Solution :

It is given that at the end of a month,

John has an account balance of : $2.75

Chary has an account balance of : - $3.00

Andrew also has savings as much as John owes the bank i.e. $2.75

The number line attached below shows the amount of money each of the three has in their account at the end of the month.

Chary owes the bank an amount that is more because $ 3.00 > $ 2.75

As the absolute value of -$3.00 is 3.00 and as $3.00 has more value than $2.75, then it turns out into $3.00 > $2.75
