Answer: 
Step-by-step explanation:
The area of a square is 
Substituting d for x, you get 1/2x^2

2 1/2 = 2 8/16
so
2 8/16 + 1 1/16 = 3 9/16
The answer is the third option
Step 1
<u>Find the value of s</u>
we know that
In a Rhombus all sides are congruent
so


equate AB and CD

Combine like term


<u>The answer Part a) is</u>
the value of s is 
Step 2
<u>Find the value of side AB</u>

substitute the value of s

Remember that the sides are congruent

therefore
<u>the answer Part b) is</u>
The length of the side BC is 
Answer:
A
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x = 
(x + 9) + 3 = 3 ( subtract 3 from both sides )
(x + 9) = 0 , then
x + 9 =
= 1 ( subtract 9 from both sides )
x = - 8
