Answer:
(a-1)²(b-1)²=a²b²+a²-b²+1²=(ab)²+(a-b)²+ 1
Answer:
If two sides of a parallelogram are represented by the vectors, then the lengths of the diagonals of the parallelogram by the parallelogram law are |→d1| and |→d2|.
The mathematical representation for the length of the diagonals is
|→d1| = | →u + → v|
|→d1| = | →u - → v|
Answer: p= 56
8 = p/7
This means to make p by itself, you have to multiple both sides by 7 to cancel out the 7. On the left side, it’d be 8 times 7, which is 56. On the right side, the 7 cancels out and isolates p.
