Q:
Help 15 pointsFind the product. (7r – 8)2(a) 49r2 – 112r + 64(b) 49r2 + 64(c) 49r2 – 112r – 64(d) 49r2 – 64r + 64
Accepted Solution
A:
Answer:49 r^2 - 112 r + 64 thus A.Step-by-step explanation:Expand the following: r (49 r - 112) + 64 r (49 r - 112) = r×49 r + r (-112): -112 r + 49 r^2 + 64 r×49 r = 49 r^2: Answer: 49 r^2 - 112 r + 64
