Why is the equation 2+2=4

Mathematics

STatiana [176]2 years ago

Answer:

Well, this is a simple equation when you look at it. Obviously, the answer is Zero. No matter how you rearrange the equation, the answer shoud always be Zero

initial equation: 2+2–4?

Altered equations:

-4+2+2?

2–4+2?

it is always the same. If i were to draw a number line, every time you add two; move two to the right, everytime i subtract four; move 4 to the left. Try it, the answer will always be Zero.

There are also acronyms: BODMAS, BIDMAS, PEDMAS Et Cetera.

these are the order(s) of operations. Search it up. If one ever comes across an equation where all operations are equivalent then solve it from left to right.

Step-by-step explanation:

The answer is 0. Why? Because of the commutative property that basically says no matter what order the numbers are in you'll always yield the same answer. (3+2=5 and 2+3=5)

In this case, 2+2-4=0 because (2+2)=4 , and 4-4=0 because 4 and -4 are additive inverses.

2+2-4=0

4-4=0

0=0

Or

2+2-4=0

2+(-2)=0

2-2=0

0=0

Find h step by step
miskamm [114]

Answer:

h = 2.7 m

Step-by-step explanation:

ΔADE and ΔABC are similar, hence ratios of corresponding sides are equal

DE / BC = AD / AB, that is

h / 0.9 = 18 / 6 ( cross- multiply )

6h = 16.2 ( divide both sides by 6 )

h = 2.7

You start driving north for 6 miles, turn right, and drive east for another 19 miles. At the end of driving, what is your straig
Anton [14]

Answer:

Okay, here's the method I'm going to use.

If you drive north 6 miles, and then drive east 19 miles, you are technically making a triangle.

                    19 miles

           l_______________

6 milesl

           l

You are just missing the last side of the triangle: the straight line stretching from across your starting point to the ending point. You can find this by using the Pythagorean theorem.

a^2 + b^2 = c^2

6^2 + 19^2 = c^2

36 + 361 = c

397 = c

\sqrt{397} = 19.924859

Rounded to the nearest tenth, your answer is

19.9 miles

25.6 % of what number is 21.12 ?
otez555 [7]

Answer:

The value of number is 82.5

Step-by-step explanation:

Given as :

Let The number  = x

∴ 25.6 % of x = 21.12

Or, 25.6 × x = 21.12 × 100

Or, 25.6 × x = 2112

∴   x = \frac{2112}{25.6}

i.e x = 82.5

Hence 25.6 % of 82.5 is 21.12  So , The value of number is 82.5  Answer
