Answer:

5 (x - 3)( {x}^{2}  + 3x + 9)

Step-by-step explanation:

5 {x}^{3}  - 135 \\  \\  = 5 \{ {x}^{3}  - 27 \}\\  \\  = 5 \{ {x}^{3}  -  {(3)}^{3}  \}\\  \\  = 5 (x - 3)( {(x)}^{2}  + (x)(3) +  {(3)}^{2} )\\  \\  = 5 (x - 3)( {x}^{2}  + 3x + 9)

Answer: If the question is asking to find the factor of 5x^3-135 then the answer is:
5(x-3)(x^2+3x+9)

Step-by-step explanation:

First, factor out the common term (x^3-27)

5(x^3-27)

Then, factor (x^3-27)

(x-3)(x^2+3x+3^2)

3^2 = 9

<u>5(x-3)(x^2+3x+9) is the answer.</u>

The inner circle circumference is 52 ft. the distance between the inner and the outer circle is 8ft. By how many ft is the outer
rjkz [21]

Answer:

The outer circle is 16 feet larger than the inner circle (68 - 52).

Step-by-step explanation:

Given that the inner circle circumference is 52 feet, and the distance between the inner and the outer circle is 8 feet, to determine by how many ft is the larger outer circle, the following calculation must be performed:

The radius of a circle is equal to half its diameter. Therefore, the radius of the inner circle is 26 feet. Thus, if the distance between the two circles is 8 feet, the radius of the outer circle is 34 feet (26 + 8). Therefore, the diameter of this circle is 68 feet (34 x 2).

This implies that the outer circle is 16 feet larger than the inner circle (68 - 52).
