Mathematics
1 answer:
Bezzdna [24]3 years ago
6 0

Answer:

18a^2

Step-by-step explanation:

Multiply the numbers together. Multiply the variables together.

(-3a)(-6a) = (-3) * (-6) * a * a = 18a^2

-3 times -6 = 18 since negative times negative is positive, and 3 * 6 = 18.

Also a * a = a^2.

Answer: 18a^2

Jan 18 Spiral Review<br> Find the surface area of the following complex shapes.
zepelin [54]

Answer:

320 in.²

Step-by-step explanation:

Let's think of the shape as a normal rectangle with a height of 16 inches. Now all we need is the length. If you look at the right corner, it looks like a piece has been cut out. Since that piece has the same length and height of 8 inches, it is a square. This tells us the missing length of the entire length of the rectangle. Now the length of the rectangle is 16 inches + 8 inches, which is 24 inches.

The total area of the rectangle is 16 × 24, which is 384.

Then from the total area, we just need to subtract the area of the cut-out part. The area of the cut-out square is 8 × 8, which is 64.

384 - 64 = 320

The total surface area of the following complex shape is 320 in.²

Zach filled 581 one-liter bottles with apple cider. He distributed the bottles to 4 stores. Each store received the same number
butalik [34]

Answer:

a. 145 liter bottles (There were 2 bottles remaining)

Step-by-step explanation:

From this question, the total number of bottles that Zach had to fill with apple cider is 581.

He has to distribute these bottles to 4 stores after filling

The question says each store received same number of bottles.

To get the number of bottles received by each store, we divide 581 by 4

= 581 / 4

= 145.25

Therefore each store gets 145 bottles each and there would be a remainder of 2 bottles
