The value of x = 75 ⇒ 2nd answer
Step-by-step explanation:
Let us revise some rules of logarithmic function
vice-versa
- If ㏑(a) = ㏑(b), then a = b
∵
- Use the 2nd rule to simplify it
∵
∵
∴ 2㏑(2x) - ㏑(10x) = ㏑(30)
- Use the 3rd rule in the 1st term
∵ 2㏑(2x) = ㏑(2x)² = ㏑(4x²)
∴ ㏑(4x²) - ㏑(10x) = ㏑(30)
- Use the 1st rule with the left hand side
∵
∴
∵
∴
- Use the 4th rule
∴ x = 30
- Multiply both sides by 5
∴ 2 x = 150
- Divide both sides by 2
∴ x = 75
The value of x = 75

Answer:
BCDE is inscribed quadrilateral. the opposite angles of a quadrilateral add up to 180°
<E = 84-180= 96°
ans is 96°
A.
We can rewrite the squared in two ways.
The first way is to rewrite it as a multiplication, this is:
The second way to rewrite the squared is by using the formula for this kind of product:
B.
Once again we can find the final result using each of the options given in part A, for the first option we have:
For the second option we have:
No matter which way we choose the answer for the squared is:
