Answer:

3(5n - 2)  \times (2n - 5)

Step-by-step explanation:

30 {n}^{2}  - 87n + 30

3(10 {n}^{2}  - 29n + 10)

3(10 {n}^{2}  - 4n - 25n + 10)

3(10 {n}^{2}  \times (5n - 2) - 25n + 10)

3(2n \times (5n - 2) - 5(5n - 2))

= 3(5n - 2) \times (2n - 5)

I HAVE 1 MORE DAY TO TURN THIS IN SO HURRY
SCORPION-xisa [38]

Hello there! I am EnjoyingLife, and I hope you find my answer helpful.

First of all, since all books cost less than $5, the most expensive a book could be is $4.99 (remember, less than, not less than or equal to)

Now, let's write an inequality to represent the cost of books.

We know that all books cost less than $5.

We have a sign for "less than". It's "<"

Thus,

p<5

Hope it helps!

Have an awesome day!

Good luck!

PLEASE HELP FAST!!! Find the surface area of the composite figure. Round your answer to the nearest tenth if necessary.
aksik [14]

Using the surface area formula for rectangular and triangular prism, the surface area of the composite figure is: 444 m².

<h3>What is the Surface Area of the Composite Figure?</h3>

Total surface area = surface area of the top triangular prism + surface area of the bottom rectangular prism - area of the surface both share together.

Surface area of the top triangular prism = (S1 + S2+ S3)L + bh = (10 + 10 + 16)5 + (16)(6) = 276 m².

Surface area of the bottom rectangular prism = 2(wl + hl + hw) = 2·(5·16+4·16+4·5) = 328 m²

Area of the surface both share together = 2(16)(5) = 160 m²

Total surface area = 276 + 328 - 160 = 444 m².
