24 and 42, I got this by multiplying 5 and 2 then doing the same thing to 7 and adding the sums. I used this method to find the perimeter of 10 and 12 as well.
There is only one solution
Answer:
Let's simplify step-by-step.
(3)(3)−(19)(2)+kx−30
=9+−38+kx+−30
Combine Like Terms:
=9+−38+kx+−30
=(kx)+(9+−38+−30)
=kx+−59
Answer:
=kx−59
Answer:
I think it is right but not sure
Hi there! The answer is 0 solutions.

First we need to work out the parenthesis (for instance possible by using rainbow technique).

Now subtract 12.

Now we can see that the right side of the equation is always 8 smaller than the left side of the equation. Because the right is always smaller, this equation cannot be solved. Therefore there are no solutions to this equation. The answer is 0 solutions.
