Answer:

16.02 m

Step-by-step explanation:

the area (A) of a square is calculated as

A = s² ( s is the side length )

given A = 256.6404 , then

s² = 256.6404 ( take square root of both sides )

s = $\sqrt{256.6404}$ = 16.02 m

First you had to add by seven from both sides of equation form.

$-7+\frac{f}{2}+7=-1+7$

Then simplify by equation.

$\frac{f}{2}=6$

Next, you multiply by two from both sides of equation form.

$\frac{2f}{2}=6*2$

And finally, simplify by equation.

$6*2=12$

$2*6=12$

$12/6=2$

$12/2=6$

$f=12$

Final answer: $\boxed{f=12}$

Hope this helps!

Which is a correct way to test whether two variables representing numbers, numone and numtwo, are equal?

bija089 [108]

You use variables for the equation and after you find out the variables you set them equal to each other and see if they are equal

As a salesperson, you are paid $50 per week plus $2 per sale. This week you want your pay to be at least $100. What is the minim

matrenka [14]

2x + 50 > = 100 (thats greater then or equal)
2x > = 100 - 50
2x > = 50
x > = 50/2
x > = 25

minimum number is 25

How do you turn 2x+3y=20 into slope intercept form?

IRISSAK [1]

Answer:

The slope intercept form of the equation is:

$y=-\frac{2}{3}x+\frac{20}{3}$

Explanation:

Given the equation;

$2x+3y=20$

We want to re-write it in slope-intercept form;

$\begin{gathered} y=mx+b \\ m=\text{slope} \\ b=\text{ y-intercept} \end{gathered}$

To do that, let us make y the subject of formula in the given equation;

subtract 2x from both sides;

$\begin{gathered} 2x-2x+3y=-2x+20 \\ 3y=-2x+20 \end{gathered}$

then divide both sides by 3 ( the coefficient of y);

$\begin{gathered} \frac{3y}{3}=\frac{-2x}{3}+\frac{20}{3} \\ y=-\frac{2}{3}x+\frac{20}{3} \end{gathered}$

Therefore, the slope intercept form of the equation is;

$y=-\frac{2}{3}x+\frac{20}{3}$
