A rectangle has a side length of 14 centimeters and an area of 98 square centimeters. Write an equation to find the length of the other side of the rectangle. Use the variable X to represent the unknown length.

a rectangle has one side ,L1 and the other side L2  the area of a rectangle is A=L1 .L2  

Step-by-step explanation

We know that L1 =14  and we know that A=98

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
