Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>Given variables:</u>
<u>Simplify, then solve:</u>
- x=2y-7
- = x = (2 * 5) - 7
- = x = 10 - 7
- = 3
- x = 3.
There are two different ways we can read your question.
Each way has a different answer.
Here it is both ways:
Way #1: (12 + 4n) / 3 = 8
Multiply each side by 3 : 12 + 4n = 24
Subtract 12 from each side: 4n = 12
Divide each side by 4: n = 3 .
====================================
Way #2: 12 + 4n/3 = 8
Subtract 12 from each side: 4n/3 = -4
Multiply each side by 3: 4n = -12
Divide each side by 4: n = - 3
Answer:
-23
Step-by-step explanation:
Let first negative integer = x
The second = x +5
Their product = 126, hence,
x * (x +5) = 126
x^2 + 5x = 126
x^2 + 5x - 126 = 0
Two numbers whose product gives - 126 and sun gives 5
x(x + 14) - 9(x+14) =0
(x - 9) = 0 or (x + 14) = 0
x = 9 or x = - 14
Since x is said to be a negative integer,, the our x = - 14
First integer = - 14
Second integer = (x + 5) = (-14 + 5) = - 9
Sum of both integers :
-14 + - 9 = - 23
Answer:
4
Step-by-step explanation:
A cube is an integer that you can get by multiplying a number by itself 3 times.
e.g.: 1 * 1 * 1 = 1; therefore 1 is a cube.
e.g.: 3 * 3 * 3 = 27; therefore 27 is a cube.
Two cubes added together can be factorized into a simpler form.
i.e.:
can be simplified into:
