Question

Which one is the answer? Answer these two

Answer 1

Answer

Expressions 4(x+5) and 5(x+4) are Equivalent

Expressions 5(2m+2) and 10m+10 are not equivalent

Step-by-step explanation:

Heres why,

4(x+5) and 5(x+4)

4 times x =4x, so multiply 4x by 5 which should give you 20.

and multiply 5 to x which would be 5x and multiply that to 4 which would be 20, they match up so they are Equivalent.

5(2m+2) and 10m+10

times 5 to 2m to get 10m and times 10m by 2 to get 20.

10m+10 = 1 which they are not equivalent

Answer 2

Answer:

x = 0

Step-by-step explanation:

4 (x+5) = 5 (x+4)

4 (x+5) = 5 (x+4)4x+20 = 5x+20

4 (x+5) = 5 (x+4)4x+20 = 5x+205x - 4x = 20-20

4 (x+5) = 5 (x+4)4x+20 = 5x+205x - 4x = 20-20x = 0
