Answer: The surface area of the triangular prism is 448 square millimeters.
To find the surface area, we just need to input our values into the formula that is given.
SA = 2B + Ph
SA = 2(84) + 56(5)
SA = 168 + 280
SA = 448
The final surface area is 448 mm^2.
Answer:(5/3,5/3)
Step-by-step explanation: I did the test ;D
-4(-x-10)= 4x• 40
11g+4-6g+7s-10 =16g+6-7s
3(10+9x)+11-3x= 13x+19
12. Both sides of the equation are equal and if 18 is half of 36 then 6×2 will give you the value of X
Eight fortyfive would most likely be the answer
