The answer could be 70a+21b
Add 10 then subtract 5 gives: 11, 21, 16, 26, 21
add 10 and subtract 5 gives: 11, 16, 21, 26, 31
When converted to a household measurement, 9 kilograms is approximately equal to a
28a⁴b: 2 · 2 · 7 · a · a · a · a · b
16ab: 2 · 2 · 2 · 2 · a · b
GCF(28a⁴b, 16ab) = 4ab
The answer is A.
