Answer:

Choice A, 20(3n-m)

Step-by-step explanation:

First, lets combine like terms for the question 54n - 20m + 6n,

60n - 20m.

Next, lets rule out the choices that are visibly wrong. This includes Choice B, because it wouldn't equal what is above and Choice C, as it ignores unlike terms.

Now, it is down to Choices A and D. Let's use the distributive property to simplify these options.

Choice A:

20(3n-m)

60n-20m

Choice D:

20(m-3n)

20m-60m

With this, it can be concluded that the correct answer is Choice A since it equals 60n-20m, which is equal to the original question when like terms are combined.

Suppose two adjacent endpoint of a rotated square are located at (-4, -6) and (5, -1) on the coordinates axes. What is the lengt
kompoz [17]
To find the length of side of square, we have to use distance formula.
Points are (-4,-6) and (5,-1)
Formula for distance between two points.
d= \sqrt{( x_{2}-x_1 )^2+(y _2-y_1)^2 } \\ 
Put \ values \\
d= \sqrt{( 5+4)^2)+(-1+6)^2  } \\ 
d= \sqrt{( 9)^2)+(5)^2 } \\ 
d=\sqrt{106} \\ 
d=10.3 \ units

So length of side of square is 10.3 units.

Answer: 10.3 units

I need the answer. Please help.
loris [4]

Answer:

44 degrees

Step-by-step explanation:

These segments form a triangle which is equal to 180 degrees. Since it forms a tangent to the circle, it forms a perpendicular angle with measure 90 degrees.

So 180 - 90 - 46 = Angle J

90 - 46 = Angle J

44 = Angle J

Use the interactive to graph these numbers on the number line. –4, 3, 0. 5, 1 Which number is closest to zero?.
lubasha [3.4K]

The number closest to 0 is the number whose absolute difference from 0 is the smallest

0.5 is the closest number to 0

<h3>How to determine the closest to 0</h3>

The numbers are given as:

–4, 3, 0. 5, 1

Calculate their absolute difference with 0

|-4 - 0| = 4

|3 - 0| = 3

|0.5 - 0| = 0.5

|1 - 0| = 1

The smallest absolute difference is 0.5

Hence, 0.5 is the closest number to 0

EleoNora [17]

Answer:

The formula for the volume of a sphere is:

Sphere Volume   =   4/3 • π • r^3

Sphere Volume   =   4/3 • π • 7^3

Sphere Volume   =   4/3 • π • 343

Sphere Volume   =   1,436.7550402417 cubic inches
