Hey 2923928 !

Answer: The second choice

$\dashrightarrow \: { \tt{(x + 3)( - {x}^{2} + 4x - 2)}}$

• from distributive property;

$\dashrightarrow \: { \tt{( - {x}^{3} + 4 {x}^{2} - 2x - 3 {x}^{2} + 12x - 6) }}$

• simplify:

$\dashrightarrow \: { \tt{ - {x}^{3} + {x}^{2} + 10x - 6}}$

Emily wants to plant flowers in an area with angular but that is 1 foot by 4.5 ft. the flowers she wants to plant need to be spa

lukranit [14]

Using the perimeter of the rectangle, it is found that she should buy at most 16 plants.

---------------------------

The perimeter of a rectangle of length l and width w is given by:

$P = 2(l + w)$

In this question, the perimeter is of 1 ft by 4.5, thus, $l = 1, w = 4.5$ , and the perimeter is:

$P = 2(1 + 4.5) = 2(5.5) = 11$

Perimeter of 11 ft.
The plants will be at least 8 inches = 2/3 feet apart along the perimeter, thus:

1 plant - 2/3 ft

x plants - 11 ft

Applying cross multiplication:

$\frac{2x}{3} = 11$

$2x = 33$

$x = \frac{33}{2}$

$x = 16.5$

At least 8 inches apart(can be more), thus she should buy at most 16 plants.
