My drawing represents 37 - 19.
The red is the leftover when you subtract.
The blue is what you took away when subtracting.
I drew 37 red circles and then took away 19 circles by coloring them blue. You are left with 18 red circles.
To find out the answer, we must see how big a centimeter and milimeter is to a standard meter 1 cm = 0.01 m 1 mm = 0.001 m 12 cm = 0.12 m 98 mm = 0.098 m, 12 cm is bigger
3/9 hope this helps let me know if i was right

Hope that helped!
Answer:
2x + 10
Step-by-step explanation:
To expand (using the distributive property) <u>multiply</u> the number outside the bracket i.e. in this case '2', with the <u>values inside the brackets</u>.
So multiply '2' and 'x' and '2' and 5' and add or subtract on basis of whether the second value is positive or negative.
So
2(x + 5)
= (2*x)+(2*5)
=2x+10
<em>extention note:</em> <u>be careful</u> when the symbol within the equation within the brackets is a subtraction because it implies that the second value would instead be a negative number and should be treated as such.
an example
2(x-5)
= (2*x)+(2*-5)
=2x -10
Anyhow, I hope this helped!
