Why is 2 the only number that is always 4 when added multiplied or squared

Mathematics
1 answer:
Alika [10]3 years ago
7 0

Answer:

There are infinite numbers that added or multiplied will give the same answer. But, if the require this two numbers to be the same, then we need to solve the following equation to see what we found out:

x + y = x * y

Given that we want the numbers to be equal, then y=x.

x + x = x * x

2x = x^2

x^2 - 2x = 0

x(x-2) = 0

We find that NOT only x=2 meets this requirement but also x=0.

Therefore, there is another number that when added, multiplied or squared gives the same result. The other number is zero!

We can prove it:

0 × 0 = 0

0 + 0 = 0

A line has a slope of 1/5 and a run = 30. What is the<br> rise?
pashok25 [27]

Answer:

<h2>rise = 6</h2>

Step-by-step explanation:

slope=\dfrac{rise}{run}\\\\\text{We have}\\\\slope=\dfrac{1}{5},\ run=30\\\\\text{Substitute:}\\\\\dfrac{1}{5}=\dfrac{rise}{30}\qquad\text{cross multiply}\\\\5rise=(1)(30)\\\\5rise=30\qquad\text{divide both sides by 5}\\\\\dfrac{5rise}{5}=\dfrac{30}{5}\\\\rise=6

The measurement of an angle is 40, and the length of a line segment is 8 centimeters the number of unique. Rhombuses that can be
Rufina [12.5K]

Answer:

The number of unique rhombuses that can be constructed is one.

Step-by-step explanation:

A rhombus is a 2D shape with 4 straight sides that are all equal length. Also opposite sides are parallel and opposite angles are equal.

The addition of the 4 angles in a rhombus is equal to 360°. We know that one angle is 40°, its opposite angle is also 40°, then the addition of the other 2 angles (which are equal) is 360° - 2*40° = 280°. The other 2 congruent angles measure 140°.

If you have the length of one side (8 cm in this case), you have the length of all sides.

In conclusion, with one side and one angle a rhombus is completely defined and it's unique.

If a nonregular hexagon has five exterior angle measures of 52, 57, 69, 54, and 54, then the measure of the interior angle adjac
goblinko [34]
All the 5 angles are equal to 286, so....
360 - 286 = 74
then,
180 aka a straight line
180 - 74 = 106

interior is 74
exterior is 106

1. A coal train in Montana starts from rest and accelerates at 2.5 m/s2 for 15s.
liq [111]

Answer:

<h3>37.5m/s</h3>

Step-by-step explanation:

If a coal train in Montana starts from rest and accelerates at 2.5 m/s2 for 15s,let us calculate the final velocity of the train.

Use the equation of motion v = u + at where;

v is the final velocity

u is the initial velocity = 0m/s (starts from rest)

a is the acceleration = 2.5m/s²

t is the time = 15secs

Substituting the given parameters into the formula;

v = 0+(2.5)(15)

v = 0+37.5

v = 37.5m/s

Hence the final velocity of the train is 37.5m/s
