Answer:
ghjggjdjhjgj;jk;l
Step-by-step explanation:
S = 2lw + 2lh + 2wh
S = 2(12)(5) + 2(12)(7) + 2(5)(7)
S = 2(60) + 2(84) + 2(35)
S = 120 + 168 + 70
S = 288 + 70
S = 358 in²
D the slopes are negative reciprocals
I am going to go with the assumption that your equation is

. If there is only one solution, then the equation must be a perfect square. So square

to solve for the equation in the similar form that is given.

. So the variables match up perfectly in the equation, meaning that the value of m is 6, letter choice C.
