Rewrite each expression by factoring out the greatest common factor 9b+12

Mathematics
1 answer:
kompoz [17]3 years ago
8 0

Answer:

  3(3b +4)

Step-by-step explanation:

The greatest common factor (GCF) of 9 and 12 is 3, so you're being asked to factor that out.

  9b +12 = 3(3b +4)

_____

The GCF can be found a couple of ways. One of them is to list the prime factors and identify those that are common.

  9b = 3 × 3 × b

  12 = 2 × 2 × 3

For these two terms, the only common factor is 3.

What is wrong with this "proof"? "Theorem" For every positive integer n,n i =1 i = (n + 1 2 ) 2 /2. Basis Step: The formula is t
creativ13 [48]

Answer:

The basis step is not even true.

Step-by-step explanation:

The basis step would be for     n = 1.

If the basis step was true then you would have that.

\sum\limits_{i=1}^{1} i  =  \frac{(1+1/2)^2}{2}

Now. When you say

                                            \sum\limits_{i=1}^{1}  i            

That's just a fancy way of writing    1.  

On the other hand    

\frac{(1+1/2)^2}{2}  = \frac{9}{4} = 2.25

Therefore  

  1 \neq 2.25

And the basis hypothesis is false.

SMART PPL PLEASE HELP ,Explain how you know the expression represents the area of shaded part of the rectangle.
MrRa [10]

Answer:

6(m-2)

Step-by-step explanation:

Alright. Let's start by finding the length of this shaded area. The full length of the rectangle is 'm', and the part that is not shaded has a length of '2', so if we subtract the full length and the non-shaded length, we will get the shaded part's length. This is 'm-2'. The width/height we already know...it is 6, so-

Answer is: 6(m-2)

Step-by-step explanation:

The rental price is 15. Add 5 per hour (5x) and the total must be equal to $50

15+5x=50

Solve for x;

5x=50-15\\5x=35\\x=\frac{35}{5}\\ x=7
