Which property is illustrated by the following statement 3z+4=4+3z

Answers

The expression 3z+4 = 4+3z represents the commutative property of addition.

What is cumulative property?

The cumulative property states that if the position of the numbers when they are in addition is changed then it will not affect the final result of the addition. If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics.

The commutative property basically states that x+y can be flipped yet have the same meaning so x+y = y+x ~

The given expression 3z+4=4+3z is showing the cumulative property of addition. By changing the position of the additional terms the final result will not change.

Therefore, the expression 3z+4 = 4+3z represents the commutative property of addition.

Matthew is paid $8.50 for each acre he mows on his grandparent's estate. He mows 50% of an acre in 3/5 of an hour.

Answers

Question

At the rate, how much will Mathew be paid for two hours of moving? Round to the nearest cent.

Answer:

exact answer =$19.83

rounded answer = $20

Step-by-step explanation:

3/5 = 0.6, so in 0.6 hours he can do 50% so in 2 hours that has 3 0.6 so 150% and the remaining time is 0.2 hours thats 1/3 of 0.6 so just divide 50% by 3 you'll get around 16.7% so in 2 hours he finished 166.7%

16.7% = 1/3 of 50% = 8.50 = 8.50/3 = 2.83

so 8.50 + 8.50 + 2.83 =

$19.83

The volume of a rectangular box is (x3 - 7x2 - 9x + 63) cubic units. Determine the dimensions of the rectangular box by factoring the volume expression completely.

Answers

Hello,
well done.
As x^3-7x²-9x+63=(x-3)(x+3)(x-7) we must have x>3 and x>-3 and x>7 thus x>7

Explanations:
x^3-7x²-9x+63=x^3-9x+(-7x²+63)=x(x²-9)-7(x²-9)=(x²-9)(x-7)=(x+3)(x-3)(x-7)
