Answer:

The equation would be:

3x + 2 = 7*2

Step 1. Subtract 2 from both sides:

3x = 6*2

Step 2. Divide both sides by 3:

3x/3 = 6*2/3
x = 2*2

A single box weights x= 4 units.

How many roots does this has? x^2+(2√5x)+2x=-10 find Discriminant

Alexxandr [17]

Given:

The equation is

$x^2+(2\sqrt{5})+2x=-10$

To find:

The number of roots and discriminant of the given equation.

Solution:

We have,

$x^2+(2\sqrt{5})x+2x=-10$

The highest degree of given equation is 2. So, the number of roots is also 2.

It can be written as

$x^2+(2\sqrt{5}+2)x+10=0$

Here, $a=1, b=(2\sqrt{5}+2), c=10$ .

Discriminant of the given equation is

$D=b^2-4ac$

$D=(2\sqrt{5}+2)^2-4(1)(10)$

$D=20+8\sqrt{5}+4-40$

$D=8\sqrt{5}-16$

$D\approx 1.89>0$

Since discriminant is $8\sqrt{5}-16\approx 1.89$ , which is greater than 0, therefore, the given equation has two distinct real roots.

Answer:

<h2> ${7}^{3} (as \: a \: single \: power \: of \: 7)$ </h2>

Step-by-step explanation:

Given 

${7}^{4} \div 7$

Since,

${a}^{x} \div {a}^{y} = {a}^{x - y}$

Hence,

$= {7}^{4 - 3}$

$= {7}^{3} (ans)(as \: a \: single \: power \: of \: 7)$
