47 -14i
You can work this out in the straight-forward way, or you can recognize that (6-i) is a common factor. In the latter case, you have ...
... = (6-i)(5 + 3-i)
... = (6 -i)(8 -i)
This product of binomials is found in the usual way. Each term of one factor is multiplied by each term of the other factor and the results summed. Of course, i = √-1, so i² = -1.
... = 6·8 -6i -8i +i²
... = 48 -14i -1
... =

Answer:
Lateral surface area = 826.5 m²
Step-by-step explanation:
Formula to calculate the lateral surface area of the triangular prism,
Lateral surface area of the triangular prism = Perimeter of the triangular base × Height
Perimeter of the triangular base = 6 + 11 + 12
= 29 m²
Height of the prism = 28.5 m
Therefore, lateral surface area of the prism = 29 × 28.5
= 826.5 m²
Answer:
1). x = 81
2). x = 84
Step-by-step explanation:
1). By applying geometric mean theorem in the given triangle,
56x = (18√14)²
56x = 4536
x = 
x = 81
2). By applying geometric mean theorem,
16x = (8√21)²
16x = 1344
x = 
x = 84
