Find the value of X in the triangular prism then round to the nearest tenth

(c, 0) i might be wrong so don't put full faith on my answer

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

answer: i can’t tell you that

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
