With expanded notation, how do u do this! ? number 15 and 16

I think that # 15 is 10,000 + 400 + 50 + 6 and #16 is 100,000 + 80,000 + 70 + 5. It's really simple to figure out; just find the number in the place value and, for how many digits after it, substitute zeros (if that makes sense).

Hope this helps!

15: 10,000 + 400 + 50 + 8

16: 100,000 + 80,000 + 70 + 5

note: hope i helped, have a great day :)

Step-by-step explanation:

The coefficients of x are different in the expressions, but the constant values are the same. Zero times any value is zero, so both expressions will be equal to –5.9. If Ryan tried any other number, he would see that the expressions are not equivalent.
