A square has an area of 144 sq. units. how long is its perimeter?
Arada [10]
Formula for Area of a square:

\boxed {\boxed {\text {Area = Length x Length}}}

Given that the area is 144 unit²:

\text {Length}^2 = 144

\text {Length} = \sqrt{144} = 12 \text { units}

Formula for Perimeter of a square:

\boxed {\boxed {\text {Perimeter = 4 x Length }}}

\text {Perimeter = } 4 \times 12 = 48 \text { units}


\boxed { \boxed { \text {Answer: The perimeter is 48 units.}}}

Find center and radius<br> (x-3)^2+y^2=8
Flauer [41]

Answer:

<h2>Center: (3, 0)</h2><h2>Radius: 2√2</h2>

Step-by-step explanation:

The equation of a circle in standard form:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the equation:

(x-3)^2+y^2=8\to(x-3)^2+(y-0)^2=(\sqrt8)^2

Therefore

the center: (3,\ 0)

the radius: r=\sqrt8\to r=\sqrt{4\cdot2}\to r=\sqrt4\cdot\sqrt2\to r=2\sqrt2

Find the slope of the line below. Enter your answer as a fraction or decimal. Use a slash mark (/) as the fraction bar if necess
Llana [10]

Answer:

1/4

Step-by-step explanation:

We can use the slope formula to find the slope

m = (y2-y1)/(x2-x1)

    = (2-0)/(4 - -4)

    = (2-0)/( 4+4)

    = ( 2/8)

    = 1/4
