Answer:

B) No Solutions

Step-by-step explanation:

|2x + 2| / 5 = -3

Multiply both sides by 5

|2x + 2| = -15

Subtract both sides by 2

|2x| = -17

Divide both sides by 2

|x| = -17

The absolute value of a number is never negative. For that reason, there are no real number solutons.

Simplify the radical, the square root of x^13

myrzilka [38]

√(x^13) is equal to:

(x^13)^(1/2) which is equal to:

(x^12*x^1)^(1/2) which is equal to

(x^12)^(1/2)*(x^1)^(1/2)

and the applicable rule: (a^b)^c=a^(b*c) so

x^(12*1/2)*x^(1*1/2)

x^6*x^(1/2)

One edge of a cube is measured and found to be 13 cm. the volume of the cube in m3 is ________.

slavikrds [6]

Since a cube is defined to have the same measurement in all three dimensions, it's volume can be calculated by raising the measurement of one side to the power of three.

In the problem we are given a measurement in centimeters and we are tasked to find the volume in m³. To make the calculation easier, we can just convert the measurement immediately since we know 100cm = 1m. Following this conversion, 13cm will be equal to 0.13m.

For the volume we'll get: $0.13^{3}=0.002197$ cubic meters or $2.197*10^{3}$ cubic meters if you are more comfortable expressing it in scientific notation.
