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:
-1 and -11
Step-by-step explanation:
"sum" means we're adding.
-1 + -11 = - 12
"product" means we're multiplying.
-1 × -11 = 11
Answer:
a= 20
b= 169.7
c= 29.71
Step-by-step explanation:
The formula of a triangle is (h*b)/2
a= (5*8)/2
b= to find the height, you can use the pythagorean theorem 18^2 - 6^2 = square root of 288. Which is 12root 2 or 16.97. (16.97*20)/2
c= using the pythagorean theorem- 11^2 = 7^2 - c^2 = square root 73, or 6root 2, or 8.49. (8.49* 7)/2
