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.

A= r2 × 3.14 7x7 ↓ ↓ 49 × 3.14 = 153.86 → 153.9

Idk i am in 5th grade lol
