Elise built a rectangular vegetable garden that is 9 feet long and has an area of 72 square feet. What is the perimeter of Elise
Papessa [141]

We have to find the width first.

72 divide by 9 = 8

To find the perimeter, you can do it two ways:

1. 9 + 8 + 9 + 8 = 34

2. 2(9) + 2(8) = 18 + 16 = 34

The answer is 34 feet.

Describe the steps in solving the linear equation 3(3x-8)=4x+6
tatiyna
Multiply everything in the parenthesis by 3.

9x - 24 = 4x + 6

Add 24 to both sides.

9x = 4x + 30

Subtract 4x from both sides.

5x = 30

Divide both sides by 5.

x = 6

Simplify tan theta times sin theta
daser333 [38]

Answer:

tan θ × sin θ

From trigonometric identities

\tan(θ)  =  \frac{ \sin(θ) }{ \cos(θ) }

So we have

\frac{ \sin(θ) }{ \cos(θ) }  \times  \sin(θ)

We have the final answer as

\frac{ \sin(θ)^{2}  }{ \cos(θ) }

Hope this helps you
