Answer:
it is a decimal which is 3.28571428571
Step-by-step explanation:
i am in college
It is 6 because 6x6x6=216
The solution of the equation are as follows:
x = 6 and y = -5
<h3 />
<h3>How to solve the system of equation?</h3>
4x + 5y = -1
-5x - 8y = 10
Therefore,
20x + 25y = -5
-20x - 32y = 40
-7y = 35
y = -5
Hence,
4x + 5(-5) = -1
4x - 25 = -1
4x = -1 + 25
4x = 24
x = 24 / 4
x = 6

Answer:
x = - 6
Step-by-step explanation:
Given
x² = 24 ( multiply both sides by 3 )
2x² = 72 ( divide both sides by 2 )
x² = 36 ( take the square root of both sides )
x = ±
← note plus or minus
x = ± 6
solutions are x = - 6, x = + 6
The smallest solution is x = - 6
We can use SOH, CAH and TOA, but first we must find the length of a hypotenuse:
