Rewrite the expression (x+3)(3x+8)-3X(x+3)

Mathematics
1 answer:
inysia [295]3 years ago
6 0
Multiply (x+3)(3x+8)      x times 3x =3x^2 then multiply x times 8 = 8x
                                 keep multiplying 3 times 3x =9x  then 3 times 8=24 
                          then multiply the -3x(x+3)=  -3x^2-9x
your hole expression will look like this 3x^2+8x+9x+ 24-3x^2-9x

if you need to simplify you can do by adding or subtracting them.
for example you can add 8x+9x= 17x

Madison is making party flavors she wants to make enough flavors so each guest gets the same number of flavors she knows there w
bazaltina [42]

Answer:


Step-by-step explanation:

To find the least number of party favors, we have to consider the number of guests.


In this case, there are two possibilities—6 or 8.


For 6: 6, 12, 18, 24 (Add 6 to each number)

For 8: 8, 16, 24 (Add 8 to each number)


Now in both series, the least number (that is in common) is 24. Hence, Madison should make at least 24 party favors.

Liam has a points card for a movie theater.
ra1l [238]

The  number of visits Liam can make to earn his first free movie ticket is: 8.4.

<h3>Number of visits Liam can make</h3>

Let x represent the number of visits

Formula
55+12.5×x=160

Re-arrange

12.5x=160-55

12.5x=105

Divide both side by 12.5x

x=105/12.5

x=8.4 visits

Therefore the  number of visits Liam can make to earn his first free movie ticket is: 8.4.

viktelen [127]

Answer:

1

Step-by-step explanation:

Let's start by prime factorizing (finding the prime factors) of 16 and 21:

16=4*4=2*2*2*2=2^4

21=3*7

We can see that they DO NOT have any common factors, meaning that their greatest common factor is 1.
