Answer: x=-17
Step-by-step explanation: Divide by -1 then add 8 to both sides and get (x+9)^3=-512, and the cube root of -512 is -8, so x+9=-8, and subtracting 9 from both sides we get x=-17 as answer.
Answer:
1/(x^3 + 6x^2 + 12x + 8)
Step-by-step explanation:
The first thing we do is rationalize this expression. (2+x)^-3 is written as
1/(2+x)^3
Then from there we can foil out the denominator. It is easiest to foil (2+x)(2+x) first and then multiply that product by (2+x).
(2+x)(2+x) = 4 + 4x + x^2
(4+4x+x^2)(2+x) = 8+8x+2x^2+4x+4x^2+x^3.
Then we combine like terms and put them in order to get:
x^3 + 6x^2 + 12x + 8
And of course we can't forget that this was raised to the negative third power, so our answer is 1/(x^3 + 6x^2 + 12x + 8)
- The area of Kayla's dollhouse upstairs = 15.15 square feet
- The area of Kayla's dollhouse downstairs = 6.45 square feet
- To find the estimated Total area of Kayla's dollhouse, we would apply the Addition Operation
- The estimated total area is calculated using the formula :
Area of the dollhouse upstairs + Area of the dollhouse downstairs
Rounding to the decimals to the nearest tenth
- The area of Kayla's dollhouse upstairs to the nearest tenth = 15.2 square feet
- The area of Kayla's dollhouse downstairs to the nearest tenth = 6.5 square feet
15.2 square feet + 6.5 square feet = 21.7 square feet
The estimated total area of Kayla's dollhouse is 21.7 square feet
