Answer:
4⋅(a⋅2)
2⋅(4⋅a)
8a
Step-by-step explanation:
(4⋅a)⋅2
4⋅(a⋅2) This is the same by the associative property of multiplication
2⋅(4⋅a) This is the same by the associative property of multiplication and the communicative property of multiplication
4⋅2⋅a⋅2 This brings in an extra 2 so it is not the same.
8a 4*2 = 8 so this is the same
4⋅2+a⋅2 This is the not the same 8+2a is not the same as 8a
Percent means “out of 100.” So 5% really means 5/100.

283136/1792 Is your CORRECT answer
Answer:
4√5
Step-by-step explanation:
c = √a² + b²
c = √4² + 8²
c = √(16 + 64)
c = √80
c = 8.94427 (rounded to nearest 1/100000)
c = 4√5
