I’m doing a lesson for iready and I had the same question
Answer:
Width =9 cm
Length =6 cm
Step-by-step explanation:
Let x be width, then length is x − 3
Let area be E. Then we have: E = x ⋅ (x −3)
54= x^2-3x
x^2-3x-54=0
We then do the Discriminant of the equation:
D=9+216
D=225
X1=3+15 over 2. which is 9
X2= 3-15. over 2. which is -6 Which is declined, since we can't have negative width and length.
Therefore x is 9. So width
So width = x = 9cm and length is x-3 = 9-3cm=6 cm
E.g. 1/4 and 1/3
The LCM of the denominators (4 and 3) is 12
So 1/4 can be written as 3/12
And 1/3 can be written as 4/12
You can then add the fractions if you wish to make 7/12
Answer:
0.1065
Step-by-step explanation:
Given :
Solution :


Taking natural log both sides
![ln[(3x+1)^5]=ln 4](https://tex.z-dn.net/?f=ln%5B%283x%2B1%29%5E5%5D%3Dln%204)
Property : 





Property : 




Hence the value of x is 0.1065
