Answer:
11
Step-by-step explanation:
3 + 
÷ 2 * 4
work for the root first
3 + 
÷ 2 * 4
3 + 4 ÷ 2 * 4
now divide 4 by 2
3 + 2 * 4
then do multiplication
3 + 8

Answer:
x = 8/3
Step-by-step explanation:
Solve for x:
6 x + 8 (5 - 7) = 0
5 - 7 = -2:
6 x + -2 8 = 0
8 (-2) = -16:
6 x + -16 = 0
Add 16 to both sides:
6 x + (16 - 16) = 16
16 - 16 = 0:
6 x = 16
Divide both sides of 6 x = 16 by 6:
(6 x)/6 = 16/6
6/6 = 1:
x = 16/6
The gcd of 16 and 6 is 2, so 16/6 = (2×8)/(2×3) = 2/2×8/3 = 8/3:
Answer: x = 8/3

Answer:
531 in²
Step-by-step explanation:
5 faces of the cube are facing the surface because the top one is shared with the triangular prism.
Surface area of a cube is S = 5 × (9)²
S = 405 in²
Now the triangular prism: S = (1/2)lP + B, where l is slant height and p is the perimeter of the base. (ignore B base area because this is also not facing the surface/shared with the cube).
S = (1/2)7×(4×9)
S = 126 in²
Add 126 + 405 to get 531 in²
