It's not B because a n(n) is always times..
It's not C because that's an Associative property..
And it is not D because that is an Identity property..
So your answer is A.

Answer:

The equation shows the commutative property of addition is  4 +3 = 3 + 4 .

Option (A) is correct.

Step-by-step explanation:

Commutative property of addition

The commutative property for addition states that

a + b = b + a .

Where a, b are any number.

thus

this above condition is satisfied by equation

4 + 3 = 3 + 4

7 = 7

Therefore Option (A) is correct.

Question 6 options: What is the approximate area of a circle with a diameter of 56 cm? Use your calculator button for π. Round y
Andrew [12]

The area of circle is 2463.0086 cm².

Step-by-step explanation:

Given,

Diameter of circle = 56 cm

Radius of circle = \frac{Diameter}{2}

Radius of circle = \frac{56}{2}=28\ cm

We know that;

Area of circle = \pi r^2

Area of circle = \pi *(28)^2

Area of circle = π * 784

Area of circle = 2463.00864041 cm²

Rounding off to four decimal places

Area of circle = 2463.0086 cm²

The area of circle is 2463.0086 cm².

Keywords: area, circle

What is the slope of a line parallel 18x+15y=90
luda_lava [24]

Answer:

-6/5

Step-by-step explanation:

Get y by itself to get the slope. So 18x+15y=90. Move 18x to the other side of the equation. Now you have 15y=-18x+90. Divide both sides by 15 to get y by itself. Now it's y= -18/15x + 6. Reduce -18/15 to the simplest fraction. You have y= -6/5x+6. Any number can replace the 6 in the equation to give you a parallel line...it's the slope that makes it parallel, not the y intercept. So y= -6/5x+10 or y=- -6/5x-1 would satisfy your parallel slope equation.
