Answer:
x = 3, x = 6
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log (
)
log
⇔ nlog x
x = n ⇔ x = 
Given
2
x - (x - 2) - 2 = 0 ( add 2 to both sides )
x² - (x - 2) = 2
(
) = 2
= 3² = 9 ( multiply both sides by x - 2 )
x² = 9(x - 2) ← distribute
x² = 9x - 18 ( subtract 9x - 18 from both sides )
x² - 9x + 18 = 0 ← in standard form
(x - 3)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 6 = 0 ⇒ x = 6
Answer: Once
Step-by-step explanation: If you do 100 - 10 you get 90 as result, therefore you don't have 100 anymore making the only logical answer to this "ONCE".
Answer:
9
Step-by-step explanation:
Side EF is 12 units, so you have to multiply 12 by 3/4, and you get 9.
Answer:
1) Arithmetic since it decreases by 3 so, -3n + 38.
2) Arithmetic since it decreases by 20 each time, so -20n+17
Step-by-step explanation:
Answer:
The square root of 49 is 7.
Step-by-step explanation:
To find the square root of 49, you would need to look at the possible multiplication equations. For example:
1 x 49 = 49
7 x 7 = 49
49 x 1 = 49
As you can see, 7 x 7 would have the square root of 49, which is 7.
7^2=49
.
In conclusion, the square root of 49 is 7
