Answer:
wow
Step-by-step explanation:
8 / 4 = 2 ;
z^8 / z^4 = z^4 ;
then, 8z^4 / 4z^4 = 2z^4 ;
finally, ( 8z^4 / 4z^4 )^ -4 = ( 2z^4 )^ - 4 = 1 / ( 2z^4 )^4 = 1 / [ 2^4 * ( z^4 )^ 4 ] = 1 / ( 16 * z^16 )
Answer:
The answer is 387. Let's see why.
Step-by-step explanation:
The computer costs $1548. And all the 12 payments are <u>equal.</u>
To find one payment we need to divide the total cost to the number of payments.
Each one of the payments is $129.
To find three payment we simply follow:
129 . 3 = <u>387</u>
Another solution can be;
Since we are looking for 3 of the payments we can divide it to the total payment
which equals to 
And we can find the answer by multiplying it with the cost which gives;
n, n+1 - two consecutive integers
n(n + 1) = 50 <em>use distributive property</em>
n² + n = 50 <em>subtract 50 from both sides</em>
n² + n - 50 = 0
-----------------------------------------------------
ax² + bx + c =0
if b² - 4ac > 0 then we have two solutions:
[-b - √(b² - 4ac)]/2a and [-b - √(b² + 4ac)]/2a
if b² - 4ac = 0 then we have one solution -b/2a
if b² - 4ac < 0 then no real solution
----------------------------------------------------------
n² + n - 50 = 0
a = 1, b = 1, c = -50
b² - 4ac = 1² - 4(1)(-50) = 1 + 200 = 201 > 0 → two solutions
√(b² - 4ac) = √(201) - it's the irrational number
Answer: There are no two consecutive integers whose product is 50.
You x all the sides together and add the 2 numbers you get
