Answer:
178.3 mm²
Step-by-step explanation:
Surface area = Base area + 3 x side triangles area
Sₐ = 43.3 + 3 x (1/2 x (10 x 9)) = 43.3 + (3 x 45) = 178.3
The answer will be 6 x 5 x 4 / 3 x 2 x 1, 5 x 4 = 20. Hope this helps
-25 15/19 + 9/1
get a common denominator of 19
they multiplied 9/1 * 19/19 = 171/19
-25 15/19 + 171/19 =
change the mixed number to an improper fraction
(19* 25 +15)/19 = 490/19
-490/19 + 171/19 =
add together
-319/19
now convert the improper fraction back to a mixed number
19* 16 =304 319-304=15
-319/19 =-16 15/19
