Answer:

The answer is A)3

Step-by-step explanation:

4 multiplied by 3 is 12, 12+12 is 24, less than 28

2 multiplied by 6 is 24+12 is 36, greater than 28

4 multiplied by 7 is 28, already over 28

4 multiplied by 10 is 40 is already way over 28

The diagonal of a square is x units. What is the area of the square in terms of X?

lesantik [10]

Answer:

$\frac{1}{2}x^2$ square units

Step-by-step explanation:

The simple formula we need here is:

$d=s\sqrt{2}$

Where

d is length of diagonal

s is length of side of square

Let's find side length of square from information given:

$d=s\sqrt{2} \\x=s\sqrt{2} \\s=\frac{x}{\sqrt{2}}$

Now,

we know area of square is $s^2$

We know s, and now we find area

Area = $s^2\\(\frac{x}{\sqrt{2}})^2\\\frac{x^2}{2}\\\frac{1}{2}x^2$

The first answer choice is right, 1/2x^2 sq. units.

Solve the equation x^2+6x+1=0

Delicious77 [7]

Hello!

x² + 6x + 1 = 0 <=>

<=> x = -6±√6²-4×1×1/2×1 <=>

<=> x = -6±√36-4/2 <=>

<=> x = -6±√32/2 <=>

<=> x = -6±2²√2/2 <=>

<=> x = -6±4√2/2 <=>

<=> x = -6+4√2/2 <=>

and

<=> x = -6-4√2/2 <=>

<=> x = -3+2√2 <=>

and

<=> x = -3-2√2 <=>

x1 = -3-2√2 and x2 = -3+2√2

Good luck! :)
