What is the system? (Is there supposed to be an image?)
A..Just plus it if not wrong
The answer is B) <span>(q - 2)(2p - 5r)
</span>2pq - 5qr + 10r - 4p = 2pq - 4p - 5qr + 10r
= 2pq - 4p - (5qr - 10r)
= 2p(q - 2) - 5r(q - 2)
= (q - 2)(2p - 5r)
<u>Answer</u>
95,040
<u>Explanation</u>
The interpretation of this expression is; the number of permutation of 5 objects out of 12.
12P5 = 12!/(12-5)!
=12!/7!
=(12×11×10×9×8×7×6×5×4×3×2×1)/(7×6×5×4×3×2×1)
=12×11×10×9×8
=95,040
