When we square brackets, it is always advised to write out the brackets fully.
(7x - 6)² becomes
(7x - 6)(7x - 6)

Next, we follow FOIL
First (The first term in the set 1 multiplied by the first term in set 2)
Outer (The first term in set 1 multiplied by the second term in set 2)
Inner (The second term in set 1 multiplied by the first term in set 2)
Last (The second term in set 1 multiplied by the second term in set 2)

F   7x  x  7x = 49x²
O  7x  x  -6  = -42x
I    -6  x  7x  = -42x
L
  -6  x  -6  = 36

Now, we add together all the terms

49x² + -42x + -42x +36

Adding a negative is the same as subtracting

49x² - 42x - 42x + 36

Finally, simplify (add together the like terms)

49x² -84x + 36

Explain the differences between a parallelogram and a rectangle.​
muminat

Answer:

<u>Similarities</u><u> between a parallelogram and a rectangle</u>

  • Quadrilateral (4-sided, two dimensional shape)
  • Opposite sides are equal and parallel to each other
  • Sum of all the interior angles is 360°
  • Diagonals bisect each other
  • Adjacent angles are supplementary (sum to 180°)
  • Opposite angles are equal

<u>Differences</u><u> between a parallelogram and a rectangle</u>

  • A rectangle has four equal interior angles (each are 90°) whereas only the opposite angles in a parallelogram are equal.
  • The diagonals of a rectangle are equal in length, whereas the diagonals of a parallelogram are not equal in length.

All rectangles are parallelograms since the opposite sides of a rectangle are parallel, but all parallelograms are not rectangles.
