6) 2(3a+1) 7) draw number line 0 to 10 and Filled circle on 3 and open circle on 8 then join the 3 and 8 together 8) h = kv = h = 8(2) h = 16 Step-by-step explanation: 6) = factor 2a * 3a+1 = 2(3a+1) we keep a inside bracket as 1 does not represent a = 2(3a+1) 7)The number line = We start with the left side which is greater than or equal to 3 - Because you had entered an equal sign, this translates to [ since we include the number 3 - We then evaluate the right side which is less than 8 - Since you did not enter an equal sign, this translates to ) since we will not be including the number 8 = Filled circle on 3 and open circle on 8 8) h = kv = h = 8(2) h = 16
