6 0

Answer:

2(4b-1)

Step-by-step explanation:

1. You would have to distribute first. So basically you just multiply 4 · 2b which gives you 8b and then 4 · 2

Answer to first step: -10+8b+8

2. Add the numbers. It should be -10 + 8 which would give you -2

Answer to second step: -2 + 8b

3. Rearranging the terms. So, instead of doing -2 + 8b you would have to do 8b - 2

Answer to third step: 8b - 2

4. 2(4b - 1) Find what times what gives you 8 (not 1 times 8) and the same for -2

Hope this helped!

A fish tank in the shape of a rectangular prism holds 30 cubic feet of water .the tank has a length of 5 feet and width of 3 fee
Flura [38]

Answer:

A - 2 feet

Step-by-step explanation:

We know that the tank is a rectangular prism which means the volume is equal to length*width*depth

since the tank can hold 30 cubic feet of water, we can divide 30 by the given dimensions of the length and width to find the depth

30/5 = 6

6/3 = 2

therefore, the depth of the tank has to be 2 feet (A)
