Can someone help me on this

Step-by-step explanation:

AX=9x+21, CX=14x+1, because AX=CX we can say

14x+1=9x+21, subtract 9x from both sides

5x+1=21, subtract 1 from both sides

5x=20. divide both sides by 5

x=4

Since CX is half of AC we can say

AC=2(14x+1)

AC=28x+2, and since x=4

AC=28(4)+2

AC=114

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
