Each answer choice below shows the entries in a row of pascal’s triangle. which lists the coefficients in the binomial expansion of (a + b)8? a)1, 7, 21, 35, 21, 7, 1 b)1, 7, 21, 35, 35, 21, 7, 1 c)1, 8, 28, 56, 70, 70, 56, 28, 8, 1 d)1, 8, 28, 56, 70, 56, 28, 8, 1

D)1, 8, 28, 56, 70, 56, 28, 8, 1

Step-by-step explanation:

The Pascal's triangle is shown in the attachment It is generated by repeating 1s at the extremes which are the coefficients of and in the binomial .The remaining entries are obtained by adding the two entries directly above it.From the attachment, the coefficients of are the entries in the last row of the triangular pattern.The correct choice is D.

Answer

16 km² + 106ha + 17,459 m²   =  17,077,459 m²

Explanation

All we need is to convert the units into the same units then add them together.

5sq.km 95ha 8449sq.m +11sq.km 11ha 9010sq.m

5sq.km + 11sq.km = 16 km²

95ha + 11ha = 106ha

8449sq.m + 9010sq.m = 17,459 m²

∴ 5sq.km 95ha 8449sq.m +11sq.km 11ha 9010sq.m = 16 km² + 106ha + 17,459 m²

   

1 km² = 1000000 m²

16 km² = 16 × 1000000

           = 16,000,000 m²

1 ha = 1000 m²

106 ha = 106 × 10000

           = 1,060,000 m²

∴ 16,000,000 m² + 1,060,000 m² + 17,459 m² = 17,077,459 m²
