<span>The communicative property for multiplication states that the order of the multiplicands and can be swapped and the resulting product stays the same.
So
A * B = B * A </span><span>
</span>So if
7*8=56
<span>then the commutative property says</span>
8*7=56 <span>as well since you can swap the order of the terms on the left and not change the result.
This property is true for addition and multiplication. It does not hold for subtraction or division.</span>
Hope that makes sense and helps. (:<span />
Answer:
11:
since diagonal are equal of rectangle
QS=RT
4x+6=6x-4
6+4=6x-4x
2x=10
x=10/2
x=5
now
diagonal :4x+6=4*5+6=<u>26</u>
12.
again
QS=RT
9x+12=11x-10
12+10=11x-9x
2x=22
x=11
now
diagonal=9*11+12=99+12=<u>111</u>
You have to divide first then subtract
The main floor has 26 rows of 29 seats each, that is 26*29 = 754 seats
And in the balcony there is 8 rolls of 23 seats, that is 8*23 = 184 seats
So the difference is 754 - 184 = 570
Then the main floor has 570 seat more than the balcony
