Answer:
x = 1/2 and 3/2
Step-by-step explanation:
The given equation is logₓ (8x-3) - logₓ 4 = 2
Then we have to determine the value of x.
logₓ
= 2 [ since log a - log b = log
]
Now
[if
b = c then
= b]
4x² = 8x -3
4x² - 8x + 3 = 0
(2x)² - 2(4x) + (4-4) + 3 = 0
[(2x)² - 2 (4x) + 4 ] - 1 = 0
(2x - 2)² = 1
(2x - 2)² = ± 1 ⇒
2x - 2 = 1 and 2x - 2 = -1
x = 3/2 2x = 1
x = 1/2
Therefore, x = 1/2 and 3/2 are the answers.
So, look:
36*4 = 144
There are 145 quarters in all.
And in nickels, there are:
144 * 5 = 720 + 5 = 725
There are 725 nickels in all.
Dimes: 144 * 10 = 1440 + 10 = 1450 (or you could do 145 * 10 and still get 1450. Like I did in the nickels and everything. :) )
= 1450 dimes
I hope this helps!
I need more information than that, to answer this question. :/

Answer:
Step-by-step explanation:
Given parameters:
Dimensions of the equilateral triangle = 6.2cm
Unknown:
Perimeter = ?
Solution:
The perimeter of the triangle is the sum of all its sides;
Perimeter = 3(L) for an equilateral triangle;
Perimeter = 3(6.2) = 18.6cm
to the nearest mm = 19.0cm
