Answer:
bottom left i think
Step-by-step explanation:
You traveled 11 miles because if you did use 28.00 and $1.50 then you take that answer and then add the $4.00 and $3.00 you will get $7 so you just subtract that for the other number and you get 11 miles because it is $1.50 per mile
1.1 Factoring: 4x2+9y2+16z2-6xy-12yz-8xz
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -6xy-12yz
Group 2: 16z2-8xz
Group 3: 4x2+9y2
Pull out from each group separately :
Group 1: (x+2z) • (-6y)
Group 2: (x-2z) • (-8z)
Group 3: (4x2+9y2) • (1)
Looking for common sub-expressions :
Group 1: (x+2z) • (-6y)
Group 3: (4x2+9y2) • (1)
Group 2: (x-2z) • (-8z)
A=1 and 2
B=2 and 4
C=1,2,7 and 14
D=1,2,4,and 8
