Naddika [18.5K]3 years ago
3 0

Answer:

The answer is 4x^2-8x-2

Step-by-step explanation:

Distribute 3 to all the numbers on the other parenthesis and the answer would be: 3x^2-6x-3

Now distribute x to that same parenthesis which would be like distributing one so it will be kept the same: x^2-2x-1

Now combine like terms:

3x^2-6x-3

x^2-2x-1

= 4x^2-8x-2

(hope this helps, sorry if I'm wrong)

Tori bought 24 candy bars for 69 cents each. She used partial products to find the total cost in cents. Which are NOT possible p
rewona [7]

Answer:

B. 36 C. 180 D. 240 E. 1,656

Step-by-step explanation:

Partial product is the multiplication of individual digit of a number in turn with each digit of the others where each digit maintains its place.

Using distributive property to multiply 24 × 69 to determine our partial products:

i.e.

24 × 69 = 24 × (60 + 9)

= (24 × 60) + (24 × 9)

= 60 (20 + 4) + 9(20 + 4)

So; we can have:

= (60 × 20) + (60 × 4) + (9 × 20) + (9 × 4)

= 1200 + 240 + 180 + 36  

= 1656

Jay works as a waiter at a restaurant.
ryzh [129]

Answer:

67.33.

Step-by-step explanation:

To figure out the tip, you need to find 20% of $52.60.

0.2×52.6=10.52

You should leave $10.52 for the waiter if you want to leave him exactly 20%.

To figure the tax, you need to find 8% of $52.60.

0.08×52.6=4.208

Next, add them up:

52.6+10.52+4.208=67.328

The total bill, including tax and tip, will be $67.33.
