Answer:

Step-by-step explanation: Proofs are important because it help with logically reasoning our problems and help us break the problem down and solve it based on assumed step that guarantee with our conclusion we are trying to prove. . Which is mathematics 101, and it helps us with logical arguments which is crucial for mathematics later down the line. Adding on to that that also means also it gives us different ways to solve problems.

In geometry, the consequences of being inaccurate is contradicting and not understanding the general properties, definitions, postulates, and theorems.

Most people use proofs for example, in court to prove whether someone is innocent or gulity.

Answer:

They are very important, it's a part of geometry. Earlier scientists gave law and theory.

Everyone knows that law is true or false , hypothesis, postulated , or etc but today everything you want to be prove you can't give proof then your law and/or theory aren't acceptable. You could a fail a math assignment, or not do good on a project at work.

One example of using a proof is in court/law. By proving someone innocent or guilty you decide their fate. If you get it wrong, it's not like failing a math test, it is someone's life, you could put them away for something they didn't do.

Answer:

Length of garden will be 30 metres.

Step-by-step explanation:

Let the Width of garden be x metres.

then,

Length of garden will be (x+6) metres.

Area = Length × Breadth

720 = x X (c+6)

720 = x²+6x

0 = x²+6x-720

As we can see above equation is a quadratic equation in the form of ax²+bx+C.

so,

$= \frac{ - b ± \sqrt{{b}^{2} - 4ac} }{2a} \\ = \frac{ - 6 ± \sqrt{{6}^{2} - 4 \times 1 \times - 720} }{2} \\ = \frac{ - 6 ± \sqrt{36 + 2880} }{2} \\ = \frac{ - 6 ± \sqrt{2916} }{2} \\ = \frac{ - 6 ± 54}{2}\\= \frac{-6+54}{2} ... \frac{ - 6 - 54}{2} \\ = \frac{48}{2} ... \frac{ - 60}{2} \\ = 24... - 30$

One of the Roots of the Quadratic equation is 24 and other is -30.

And as we know width of any garden cannot be negative so the width of garden will be 24 metres.

As we got the width,

adding 6 to it will give us the Length,

So,

24 metres + 6 = 30 metres.

Length of the garden is 30 metres.

Hope It Helped You ;)

Answer:

2x3 - 3x + 4

———————

Step-by-step explanation:

Step 1 :

Simplify ——

Rewriting the whole as an Equivalent Fraction :

4.1 Adding a fraction to a whole

Rewrite the whole as a fraction using x2 as the denominator :

x x • x2

x = — = ——————

1 x2

Let us test ....

P Q P/Q F(P/Q) Divisor

-1 1 -1.00 5.00

-1 2 -0.50 5.25

-2 1 -2.00 -6.00

-4 1 -4.00 -112.00

1 1 1.00 3.00

1 2 0.50 2.75

2 1 2.00 14.00
