Answer: CD=18
Explanation: Use the side-splitter theorem and solve.
1) (3/x)=(4.5/(x+6)), cross multiply and solve for x
2) 6x+36=9x
3) x=12
4) Solve for CD
5) (12)+6=18
It took her 4 hours.
Since she travels 50 miles in just one hour, in four hours she could drive 200 miles. :)

Answer:
The greatest number of platters he can prepare is 3.
Step-by-step explanation:
Given : In preparation for a party, brant is putting desserts onto platters. the chocolate cake is cut into 15 pieces and the cheesecake is cut into 6 pieces. if he wants to prepare identical platters without having any cake left over.
To find : What is the greatest number of platters he can prepare?
Solution :
The greatest number of platters he can prepare is given by finding the GCF of 15 and 6.
Factoring the numbers,


The GCF is the greatest common factor.

Therefore, the greatest number of platters he can prepare is 3.
Answer:
see explanation
Step-by-step explanation:
Using the laws of logarithms
• log x - log y = log(
)
•
x = n ⇔ x = 
Hence
(
) = 2, hence
= x² ( multiply both sides by 4 )
8x - 3 = 4x² ← rearrange into standard form
Subtract 8x - 3 from both sides
4x² - 8x + 3 = 0 ← in standard form
(2x - 1)(2x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = 
2x - 3 = 0 ⇒ 2x = 3 ⇒ x =
