Step-by-step explanation:
3+4+ 5+ 3+ 4+ 5+ 6+ 7+ 1+ 2+ 3+ 4+ 5+ 6+ 4+ 8+ 4+ 3+ 2= 79
79/ 19 = 4.1
Answer: x = { 2 ; 3 }
+) x² - 3 = x² - 1 - 2 = (x - 1)(x + 1) - 2
+) x² - 3 is divisible by x-1 but (x -1)(x + 1) is divisible by x-1
=> 2 must be divisible by x-1
=> x - 1 is divisor of 2
=> (x - 1) ∈ {-1; 1; 2; - 2;}
but x > 1 => x - 1 > 0
⇒ x - 1 = {1; 2; }
+) with x - 1 = 1 => x = 2
x - 1 = 2 => x = 3
Step-by-step explanation:
Answer:
16.75 meters
Step-by-step explanation:
This problem is a plug in problem.
H = 0.20x + 12.75
we plug in 20 for x which gives us
(0.20 * 20) + 12.75
which equals
4 + 12.75
giving us
16.75 meters
