Me plz which expression, when simplified, is equal to 7p? a) 9p – 2pq – 7p – 5p + 2pq b) 9p – 2pq – 7p + 5p – 2pq c) 9p + 2pq – 7p + 5p – 2pq d) 9p + 2pq + 7p + 5p – 2pq

The answer is option (C) 9p+2qp-7p+5p-2pq if you see the expression you will note that +2pq and -2pq will cancel each other out as they are equal now remaining are +9p-7p+5p if you take p commomn from this expression it becomes p(9-7+5) and 9-7+5=7 so final expression will be 7p as required in the question

The answer is "a"radius = 12.7 unitsdiameter = radius × 212.7 units × 2 = 25.4 units
