Step-by-step explanation:

you have to multiply 5 with all the value inside the bracket,then you will get 10x-20+15x.

as it has the same term,you can add 10x with 15x.and you will get 25x -20.

C and D

Step-by-step explanation:

Looking at 5(2x - 4 + 3x), we use the distributive property to expand it out. In other words, we multiply 5 by every term within the parentheses:

5 * 2x + 5 * (-4) + 5 * 3x = 10x - 20 + 15x

Already, we see this matches choice C.

However, we can also combine like terms with the x terms:

10x - 20 + 15x = 25x - 20

This matches choice D.

Thus, the answers that are correct are C and D.

by good luck mark me as brainliest

have a nice day

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
