Answer:
Step-by-step explanation:
Rewrite this expression as (27^(1/3) )². this is equivalent to:
( ∛27 )² or (∛27)(∛27).
If you wish to evaluate this expression, it is ( 3 )( 3 ) = 9.
Let the required number is 2x ,
According to the condition,
➡ 10 times the sum of half of 2x and 6 = 8

Therefore the value of x is -5.2
And, required number is -5.2
Answer:
B. -40°F
Step-by-step explanation:
its- clearly lower than -30
9 5/6 - 2 1/3 is 7 1/2.
You could get this answer by finding the same denominator of the fractions. The LCM of both is 6. Multiply the 1 of the second fraction 2 times because you had to multiply the denominator 2 times to get to 6.
You should have 2 2/6.
Now get 9 5/6 - 2 2/6.
The answer is 7 3/6, simplifies into 7 1/2.
9 5/6 - 2 1/3 is 7 1/2.
Answer:

Step-by-step explanation:
Biquadratic Equation
It's a fourth-degree equation where the terms of degree 1 and 3 are missing. It can be solved for the variable squared as if it was a second-degree equation, and then take the square root of the results
Our equation is

If we call
, our equation becomes a second-degree equation

Dividing by -3

Factoring

It leads to these solutions

Taking back the change of variable, we have for the first solution

Now for the second solution, we get imaginary (complex) values

Summarizing, the four solutions for x are
