Find the indicated cardinal number Find n(AxB) given that n(A)=31 and n(B)=9
A. 40
B.279
C.22
D.49

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

step-by-step explanation:

i reviewed this question with a peer and teacher, seems to be correct, me later

range =5
