Exactly like the previous question you posted.

-3x² - 9x = 0

Divide each side of the equation by -3 :

x² + 3x = 0

Factor the left side:

x (x + 3) = 0

This is true if x=0 or if x=-3 .

$-3x^2-9x=0\\
-3x(x+3)=0\\
x=0 \vee x=-3$

kondor19780726 [428]

Answer:

P = 25.6 feet

Step-by-step explanation:

Given that,

Rectangle A and B have the same Area.

The area of a rectangle is given by :

A = lb

$l_Ab_A=l_Bb_B$

We have,

$l_A=7\ m, b_A=4\ m, b_B=10\ m$

So,

$l_B=\dfrac{l_Ab_A}{l_B}\\\\l_B=\dfrac{7\times 4}{10}\\\\l_B=2.8\ m$

The perimeter of rectangle B,

$P=2(l_B+b_B)\\\\=2(2.8+10)\\\\=25.6\ ft$

So, the perimeter of rectangle B is equal to 25.6 feet.
