Answer:
D
Step-by-step explanation:
Given
(x - 5)³ = (x - 5)(x - 5)(x - 5)
Expand (x - 5)(x - 5) using FOIL then multiply the result by (x - 5)
(x - 5)(x - 5)
= x² - 5x - 5x + 25 = x² - 10x + 25, then
(x - 5)(x² - 10x + 25)
= x(x² - 10x + 25) - 5(x² - 10x + 25)
= x³ - 10x² + 25x - 5x² + 50x - 125 ← collect like terms
= x³ - 15x² + 75x - 125 → D
The answer is about 36.9%
I just guessed and checked. 95-60= 35
So .3685×95 is the closest to equaling 35
Answer:
D) p³ + 2; when p = 3 the number of plants is 29.
Step-by-step explanation:
Illiana cubed (³) the number of original plants, p, in the garden. Then, she added 2 more plants. We will use n for the number of total plants.
So, the equation should be p³ + 2. Substitute our value for p into the equation and solve.
p³ + 2 = n
3³ + 2 = n
27 + 2 = n
29 = n
There are 29 total plants.
The answer, then, is the last option, p³ + 2; when p = 3 the number of plants is 29.
Good luck ^^
Cubert (x^2) * cubert(x^2)=
Since they're both cube roots you can multiply the radicands.
Cube root (x^4)=
x cube root x
