Answer:
(2, -6)
Step-by-step explanation:
5n^2+20n-60
(5n+30)(n-2)
5n + 30 = 0
5n = -30
(5n = -30)/5
n = - 6
n - 2 = 0
n = 2
answer: (2, -6)
Answer:
x = 35
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Then
1 exterior angle = 360° ÷ 8 = 45° , so
x + 10 = 45 ( subtract 10 from both sides )
x = 35

Answer:
- 3
Step-by-step explanation:
Using the law of logarithms
x = n ⇔ x =
let ( ) = n
( ) = n, then
=
Since bases are the same on both sides then equate the exponents
⇒ n = - 3 → (4)
