e is the base of the natural log system.

take the natural log of both sides.

ln(e^a) = ln(60) The power can come down

a ln(e) = ln(60) The natural log of e = 1

a * 1 = ln (60)

a = ln(60)

Answer:

Area of gray region = $8x^2+8x-7$

Step-by-step explanation:

The area covered by the furniture can be subtracted from the total area of the room to calculate the area of the gray region.

<em>Total</em> area of the room: $13x^2+7x-2$

Area taken up by furniture: $5x^2-x+5$

Area of gray region = total area of the room - area taken up by furniture

Area of gray region = $13x^2+7x-2-(5x^2-x+5)$

Remember to distribute the negative sign:

Area of gray region = $13x^2+7x-2-5x^2+x-5$

Combine like terms:

Area of gray region = $8x^2+8x-7$

How to factor 4x^2+24x+27

fomenos

Answer:

(2 x + 3) (2 x + 9)

Step-by-step explanation:

Factor the following:

4 x^2 + 24 x + 27

Factor the quadratic 4 x^2 + 24 x + 27. The coefficient of x^2 is 4 and the constant term is 27. The product of 4 and 27 is 108. The factors of 108 which sum to 24 are 6 and 18. So 4 x^2 + 24 x + 27 = 4 x^2 + 18 x + 6 x + 27 = 9 (2 x + 3) + 2 x (2 x + 3):

9 (2 x + 3) + 2 x (2 x + 3)

Factor 2 x + 3 from 9 (2 x + 3) + 2 x (2 x + 3):

Answer: (2 x + 3) (2 x + 9)
