For all of these answers, the equation used was (AB + CD)/2 = EF
1.12+24=36 36/2=18
2. 21 + 35 = 56 56/2 = 28
3. (7 + EF)/2 = 9
multiply by 2
7 + EF = 18
subtract 7
EF = 11
4. (AB + 32)/2 = 22
Multiply by 2
AB + 32 = 44
Subract 32
AB = 12

Answer: 1) 2.059
2) 3.220
<u>Step-by-step explanation:</u>
1) log₆ 40
= log₆(5 x 8)
= log₆5 + log₆8
= 0.898 + 1.161
= 2.059
2) log₆ 320
= log₆ (40 x 8)
= log₆40 + log₆8
= 2.059 + 1.161
= 3.220
Distance between two points is
Root of X2 - X1 squared + Y2 - Y1 squared
So here X2 is 0 X1 is 0 as the origin is 0,0
Root of Y2-Y1 squared is what we are left with
Root of -2- -3 squared
Root of 1 squared
Root of 1
Which is 1
Distance is 1
