Answer:

A rational exponent is an exponent that is a fraction. If the fraction has an even denominator, the root will be of an even number (like the square root, the 4th root, etc.). Think about it when you square something: -2 • -2 = 4, 2 • 2 = 4. No matter the sign, any number multiplied by itself an even number of times will make a positive number. So, you can't take the square root of a negative number because it is impossible to get a negative number when squaring! This applies to ALL even roots/exponents. So, (-1)^½ does not exist! Look: (-1)^½ becomes √(-1) which is an imaginary number!

A rectangle is 10 feet longer than it is wide. The area is 39 square feet. Find the dimensions of the rectangle​
soldi70 [24.7K]

Answer:

length = 13 ft

Width = 3 ft

Step-by-step explanation:

Width = w ft

Length = ( w +10 ) ft

Area = 39 square ft

length * width = 39

(w +10)* w = 39

w *w + 10*w = 39

w² + 10w - 39 = 0

w² + 13w - 3w - 3*13 = 0

w(w + 13) - 3(w + 13) = 0

(w + 13) (w - 3) = 0    {Ignore w + 13 , as measurement cannot be in negative}

w - 3 = 0

      w = 3

length = 3 +10 = 13 ft

Pls help on both questions
WINSTONCH [101]

Answer:

Step-by-step explanation:

Both expression are the same :

14 = 2(x + 3)

By expansion :

14 = 2*x + 2*3

14 = 2x + 6

Hence ;

Both expression are the same

Weight of one circle :

Final weight on both sides are equal:

Weight on Left hand side = 14

Weight on right hand side = 3*x + 3*x

Weight on Left hand side = Weight on right hand side

14 = 3x + 3x

14 = 6x

x = 14 / 6

x = 2.333
