Yes "3x8 = 4x6" does illustrate the commutative property of multiplication.
You can do 1st $12.60 divided by 100 is 0.126 then you do 0.126x10= 1.26 then you add the special price which is $12.60 plus $1.26= $13.86 that is the original price for the dinner.
Answer:
Below.
Step-by-step explanation:
We apply the quotient rule:
dy/dx = ( tanx * 3x^2 - x^3 * sec^2x) / (tan^2 x)
= x^2( 3tanx - xsec^2x) / tan^2x
Answer:
26 units

im not sure if this will help but i counted the spaces and added the halves
Answer:
<h2>|DB| = 6</h2>
Step-by-step explanation:
If ABCD is a rhombus then the diagonals AC and BD are perpendicular and intersect in half.
Let E be the point of intersection of the diagonals.
Therefore:
AE ≅ EC and DE ≅ EB ⇒ |AE| = |EC| and |DE| = |EB|.
DB = DE + EB
|EB| = 3 ⇒ |DB| = 3 + 3 = 6
ABCD it's not a rectangle because in each rectangle diagonals are congruent and intersect in half.
