Answer:

The length of the rectangle is 31.

Step-by-step explanation:

We have that the length (L) and width (W) are:

L = 3x + 7

W = 2x

The perimeter of the rectangle is given by:

P = 2W + 2L

94 = 2(2x + 3x + 7)

94 = 10x + 14

x = 8

Now, we can calculate the length of the rectangle:

L = 3x + 7 = 3*8 + 7 = 31        

         

Therefore, the length of the rectangle is 31 units.

I hope it helps you!

The mass of an adult North Pacific right whale is about 70,000 kg, or 7 x 104
olasank [31]

Answer:

Answer B: 1*10^2 times

Step-by-step explanation:

To find how many times more massive is the whale relative o the polar bear, we just need to find the quotient of one over the other:

\frac{7*10^4}{7*10^2} = \frac{7*10^2*10^2}{7*10^2}=1*10^2 times

Therefore our answer agrees with the one shown as answer B.

I'm going to assume you mean 3 to the power negative 5.

3^-5

Use rule [ x^-y = 1/x^y ]

3^-5 = 1/3^5 = 1/243

Best of Luck!
