9
The expression equivalent to 72 plus 9 is 81. This is calculated by simply adding the two numbers together: 72 + 9 = 81.
9(8 + 1)
It is: 9*(8+1) = 81
The expression (72 9) typically represents the greatest common divisor (GCD) of the numbers 72 and 9. To find this, we can determine the factors of both numbers. The GCD of 72 and 9 is 9, as 9 is the largest number that divides both without leaving a remainder. Therefore, (72 9) is equivalent to 9.
To find an expression equivalent to 54 ÷ 72, we can simplify the fraction by dividing both numbers by their greatest common factor, which is 18. So, 54 ÷ 18 = 3 and 72 ÷ 18 = 4. Therefore, the expression equivalent to 54 ÷ 72 is 3 ÷ 4, which simplifies to 3/4.
-12i(3-6i) = -36i + 72i² = -36i + 72 × -1 = -36i - 72 = -72 - 36i = -36(2 + i)

The expression ( \sin(72^\circ - a) ) can be rewritten using the sine difference identity: [ \sin(72^\circ - a) = \sin(72^\circ) \cos(a) - \cos(72^\circ) \sin(a). ] Thus, ( \sin(72^\circ - a) ) is equal to ( \sin(72^\circ) \cos(a) - \cos(72^\circ) \sin(a) ).
The expression 9+5 is equivalent.
40 + 32 = (5 x 8) + (4 x 8) = 9 x 8 = 72
