Answer:-2
Step-by-step explanation:
The surface area of the prism will be given by:
SA=2(L×W)+2(L×H)+2(H×W)
SA=2(12×5)+2(12×9)+2(5×9)
SA=120+216+90
SA=426m²
Answer: 426m²
Answer:
number = 9
Step-by-step explanation:
number = x
3 is added to a number = (x+3) result
3 times the number = 3x
15 less than three times the number = 3x-15
the results is 15 less than three times the number
x+3 = 3x -15
3x-x= 3+15
2x = 18
x=9
Answer:
b) 7 over 12 or (7/12)
