Answer: p^2 + 4q^2 + r^2 + 4pq + 4qr + 2pr
Explanation:
We need to expand (p+2q+r)^2
We know that (x+y+z) ^2 = x^2 + y^2 + z^2 + 2xy + 2yz + 2xz
Here x = p,y = 2q and z = r
Therefore (p+2q+r)^2 = (p)^2 + (2q)^2 + (r)^2 + 2(p)(2q) + 2(2q)(r) + 2(p)(r)
= p^2 + 4q^2 + r^2 + 4pq + 4qr + 2pr
Answer:
Soybeans
Explanation:
Soy beans is an example of increased farming variety beginning in the 1970s. The 1970s period has been characterized broadly as a period of great farm prosperity, this is likely caused by a short period of high farm income.

Answer:
The Battle of Antietam was fought on September 17, 1862, during the Civil War. The Commander-in-Chief of the Union was George B. McClellan, while Robert E. Lee was Commander-in-Chief of the Confederation. It was the bloodiest one-day battle in American history, with 22,717 dead.
The battle was fought at Sharpsburg and the Antietam Basin, west of the state of Maryland. Although McClellan had plenty of reserve forces that could be used to exploit local successes in the battle, he failed to destroy Lee's army. McClellan had halted Lee's invasion of the state of Maryland, but Lee managed to withdraw his forces to Virginia without interruption from the cautious McClellan. Although the battle was tactically ambiguous, Confederate forces initially withdrew from the battlefield. This made the battle, in military terminology, a Union victory. The victory was significant enough to give President Abraham Lincoln the confidence to announce his Emancipation Proclamation. This in turn led to the British and French governments departing from their plans for recognition of the Confederacy.
