9 squares because if there are 18 triangles in it then you divide 18 by 2 and get 9
X would equal 9. Subtract 18 from both sides then divide by two to get 9 as X
If you see that 3x-3 and set it equal to x+7 then you will get this,
3x-3=x+7
Now solve for X. You will get 5.
Then you plug five in and get 12 For both sides and then multiply 12 by 4 and get 48.
You answer is 48.
Hope this helps you.
You use distributive property. So (5 x 2)-(5 x x)= 10 - 5x.
Answer: 13 is a rational number
Step-by-step explanation: By definition, a rational number is a number q that can be written as a fraction in the form q=a/b where a and b are integers and b≠0. So, 1/3 is rational because it is exactly what you get when you divide one integer by another.
