Which property of multiplication is shown below?If x = a + bi and y = c + di, x × y = y × x.

Answers

There are four properties of multiplication namely commutative, associative, multiplicative identity and distributive. The equation given defines the commutative property of multiplication where two numbers are multiplied, the product will still be the same no matter what is the order of the multiplicands.

Answer:

Step-by-step explanation:

The given values of x and y are:

$x=a+bi$ and $y=c+di$

Then, using the commutative property which states that it is a binary operation in which ab=ba whenever you change the order of the operands.

Therefore, $xy=yx$

$(a+bi)(c+di)=(c+di)(a+bi)$

$ac+bci+adi+bdi^2=ca+dai+cbi+dbi^2$

$ac+(bc+ad)i-bd=ca+(da+cb)i-db$

Thus, commutative property of multiplication is as shown above.

If 6.3% of your salary is deducted for a fund how much would be deducted from a $488.00 weekly salary

Answers

the issue is to find the 6.3% out of $488, that is easy, just multiply them both and remember that 6.3% is 6.3 out of 100, 6.3/100
deduction = 6.3%($488)
= (6.3/100)(488)
= 30.74
hence, will be deducted $30.74 which is 6.3% of $488

Choose the correct simplification of the expression (−2x + 8y)(9x − 3y).−18x2 + 78xy − 24y2
18x2 + 78xy − 24y2
−18x2 − 78xy + 24y2
−18x2 + 72xy − 24y2

Answers

For these kinds of expressions use FOIL (first, outside, inside, last).

-2x • 9x = -18x^2
-2x • -3y = 6xy
8y • 9x = 72 xy
8y • -3y = -24y^2

Now combine them all:

-18x^2 + 78xy - 24y^2

James has $120 in his saving account and plans to have $x each month for 6 months. the expression $6x $120 represents the total amount in the account after 6 months. factor the expression 6x 20

Answers

2(3 * 10) is 6 x 20 factored

Answer:

6(x+20)

Step-by-step explanation:

6x: 2*3

120: 2*2*3*5

The GCF of 6x*120 is 2*3

so the factored expression is 6(x+20)

A square has a perimeter of 28 feet.
What is its area?

Answers

Since the formula for the perimeter of a square is 4s then
4s=28
s=7

Now the area of square is s^2=a
(7)^2=a
49=a

Answer: 49 feet squared

A square has four equal sides. It the perimeter is 28, then each side is 7 feet. The area is just the side length squared. 7 times 7 equals 49
