Answer:
1) 7m
2) 13
3) 4x^2y
4) 6s^3t^4
Step-by-step explanation:
gcf means the the greatest factor that works for both terms
1) 21m^3 and 28m
let's first find the gcf for the coefficient
21 and 28, the gcf is 7. (hopefully thats easy to explain)
the gcf for the variables is the same mindset as the numbers
m^3 and m, both can be factored by m
so the gcf is 7 * m which is 7m
2)
13x and 26
let's first find the gcf for the coefficient
13 and 26, gcf is 13
there's only one variable, x, so there's not gcf for that
so the gcf is just 13
3)
8x^2y and -12x^3y^2
let's first find the gcf for the coefficient
8 and -12, the gcf is 4 (you can also say -4)
for the variables , same mindset
x^2y and x^3y^2
the gcf for x is x^2, and for y it is just y
so 4 * x^2 * y = 4x^2y
by understanding 3) hopefully you can understand 4)
pls comment for any questions
Answer:

Step-by-step explanation:
Given


Required
Determine the rate of change.
From the given parameters, we understand that the on a daily basis, there's a charge of $0.05.
This charge represent the rates at which the fee changes on a daily basis.
Hence:

Answer:
1) you can make 32 bows
2) a. 16 b.8
Step-by-step explanation:
1) if you have 16 meters of ribbon and it takes 1/2 meters to make one now, you would divide 16 by 1/2 and get 32
2)if you divide 8 by 0.5 you get 16 and if you divide 4 by 0.5 you get 8
From the definition of logarithm, we know that:

In this case

and

so:
Answer:
Option B: 3(27b + 9c - 5d)
Step-by-step explanation:
The equation is actually 8lb+ 27c - 15<u>d</u>
A common factor is 3:
3(27b + 9c -5d)
Option B: 3(27b + 9c - 5d)
