Answer:

4x^3 + 5

Step-by-step explanation:

(6x^3 - 4) + (-2x^3 + 9)

You can get rid of the parentheses

6x^3 - 4 + -2x^3 + 9

Combine like terms

6x^3 + -2x^3 = 4x^3

-4 + 9 = 5

4x^3 + 5

Answer:

Please check the explanation.

Step-by-step explanation:

Ascending Order:

When we talk about the numbers to be arranged in ascending order, it means the numbers need to be arranged from smallest to largest.

For example, if we have to arrange the numbers from 1 to 5 in ascending order.

It means, the ascending order will be: 1, 2, 3, 4, 5

Now, let us arrange the given numbers in ascending order.

a) 2234 to 2238         2234          2235            2236          2237          2238

b) 4099 to 4103          4099          4100             4101            4102          4103

c) 3298 to 3302          3298          3299            3300         3301           3302

d) 7269 to 7273          7269          7270            7271            7272          7273

e) 6354 to 6358          6354           6355           6356           6357          6358

f) 8379 to 8383           8379           8380            8381           8382          8383

g) 7365 to 7369          7365           7366           7367           7368          7369
