Factored: 6(3n+2)
6 is the greatest common factor of 18n and 12 so you change it to distributive property by factoring it to 6(3n+2)
if you distribute 6(3n+2) you get 18n+12
Answer:
There are 35 dogs in the pet home.
Step-by-step explanation:
3:5 is the ratio, 3 being cats and 5 being dogs
Since there are 21 cats, you would do 21/3 to find the ratio value - which is 7
Now, multiply 5 times 7 to get the amount of dogs, which is 35.
Answer:
36x^2
Step-by-step explanation:
Let's first get rid of the 4 in the denominator by simplifying.
(4sqrt(9x^3))/(sqrt(4x))
Now square the top and bottom to get rid of square roots.
16(9x^3)/(4x)
Simplify again.
4(9x^2)
Combine
36x^2
Answer:
No for the first one, yes for the second.
Step-by-step explanation:
Plug in the given numbers and see if it works.
15(1) + 3(4) = 10
15 + 12 = 10.
27 ≠ 10
Since 27 does not equal 10, we can already see that solution (1,4) will not work for these equations.
Now for the second problem, do the same thing.
10 = 1 + 9.
This is true, but remember to check the second equation just to be sure.
10 = 4(1) + 6
10 = 4 + 6
This is also true, so it (1,10) is a solution for the second system of equations.
The answer is C.1/2 because there is only possible numbers are 3,5,6.
