There are infinitely How many pairs of numbers of which the sum of their cube roots is zero give two of these pairs
ivanzaharov [21]

Answer:

Infinite pairs of numbers

1 and -1

8 and -8

Step-by-step explanation:

Let x³ and y³ be any two real numbers. If the sum of their cube roots is zero, then the following must be true:

\sqrt[3]{x^3}+ \sqrt[3]{y^3}=0\\ \sqrt[3]{x^3}=- \sqrt[3]{y^3}\\x=-y

Therefore, any pair of numbers with same absolute value but different signs fit the description, which means that there are infinite pairs of possible numbers.

Examples: 1 and -1; 8 and -8; 27 and -27.

He sum of the interior angles, s, in an n-sided polygon can be determined using the formula s = 180(n 2), where n is the number
Evgesh-ka [11]

Answer:

9

Step-by-step explanation:

Equation

Sum = s  = 180*(n - 2)

Solution

1260 = 180*(n - 2)             Divide by 180

1260 / 180 = 180 * (n -2 ) / 180

7 = n - 2                             Add 2 to both sides

9 = n            

Answer

The polygon has 9 sides.

HELP ILL GIVE BRAINLIEST
SVETLANKA909090 [29]

Answer:

\huge\boxed{\bf\:c = \frac{11}{4}}

Step-by-step explanation:

4c + 2c = 4c + \frac{11}{2}

Cancel 4c on both the sides of the equation.

2c = \frac{11}{2}

Bring the 2 in the denominator of 11/2 to the left hand side of the equation.

2*2c = 11\\4c = 11

Bring 4 to the right hand side if the equation.

\boxed{\bf\:c = \frac{11}{4}}
