If you're completing the square the answer is in the image.

If i have 6 bottles of water and each weigh 3/5 pounds how much do i have
Katen [24]

You have 3 and 3/5 pounds of water.

To find this, simply multiply 3/5 by 6/1 (multiplying straight across). 6 times 3 is 18 and 5 times 1 is 5. Thus meaning you have 18/5 pounds, which simplified is 3 and 3/5 pounds.

I hope this helps!

What’s the surface area
STALIN [3.7K]

Answer: 38 in.^{2}


Step-by-step explanation:

1/ Find the area of the triangular sides. (1/2 x 2 x 6 = 6 in.^{2} for each triangular side)

2/ Find the area of each of the rectangular sides. In this case, the bottom (base) side is 2x6 = 12 in^{2}. The rectangular side on the left is 2x3 = 6 in.^{2}, and the rectangular side on the right is 4x2 = 8 in.^{2}.

3/ Add everything together. Rectangular Sides + Triangular Sides = Surface Area ---> 12 in.^{2} + 6 in.^{2} + 8 in.^{2} + 6 in.^{2} + 6 in.^{2} = 38 in.^{2}

4/ You have your answer, now hope it helps ! :)

Which expression shows how 6 • 45 can be rewritten using the distributive property?
tatuchka [14]
6*45=270 is the first step you should do to get the answer you are looking for. The next thing I would do is go to all the answers to see which one comes out the same way. The first one comes to be 246, the next one is 54, the next is 270 and the last one is 220. 6*40+6*5 is the correct answer.
