I need to know the answer to the second one.

Debora [2.8K]

Travis got 43 dollars

Robin collected 35 percent more so we can model this with

Travis + (Travis x .35)

43 + 15.05 =58.05

Jessica colelcted 20 percent less so

Travis - (Travis x .20)

43 - 8.6 = 34.3

34.4 + 58.05 + 43 = 135.45

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

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.
