Answer:
48
Step-by-step explanation:
The square pyramid has exactly the same four triangles.
In order to find the whole surface area, we must find the area of one of the triangles and multiply them by 4.
Surface area of square pyramid = 
Where we know that b = 4 and h = 6.
Substituting into the formula should give us the answer 48.
Conjugate of 9-5i is 9+5i
product of those two: (9-5i)*(9+5i) =
<span>Let x be the number. By the given above, the relationship between the numbers and the newly-introduced variable is expressed as (2/5)(x) = 14. To determine the value of x, divide 14 by 2/5. This will give us the answer which is equal to 35. Hence, the answer to this item is 35. </span>
