mars1129 [50]

Answer:

C and D

Step-by-step explanation:

The area of a rectangular raised garden bed for growing beets is given by the expression $(3b)(3b-3).$

The area of the rectangle is

$A=\text{Width}\cdot \text{Length}$

Thus,

$\text{Width}=3b\\ \\\text{Length}=3b-3$

$\text{Width}=3b-3\\ \\\text{Length}=3b$

The length of the mat is greater than its width. Since

$3b>3b-3$

then

$\text{Width}=3b-3\\ \\\text{Length}=3b$

Options A and B are false, options C and D are true.

Answer: " -2y³ + 3y²<span> + 27y " .
_______________________________________________________
Refer to the completed chart below (image attached).</span>
_______________________________________________________
Using the completed chart below (image attached), we can write out the terms:
__________________________________________________
y³ − 3y³ + 9y² + 3y² − 9y² + 27y ;

Then, we can combine the "like terms" ;
__________________________________________
y³ − 3y³ = -2y³ ;

+9y² + 3y² − 9y² = + 3y² ;
___________________________________________________________
to get: -2y³ + 3y² ; and bring down the "+27y" ;
