is it possible to find a side length that would be perfect for a square with an area of 45 square units?
Cerrena [4.2K]

If a square has an area of 45 square units its side has a length of

s=\sqrt{45} = 3 \sqrt{5}

units.  Is that a perfect length?  I don't know, but I know it's perfect for a square whose area is 45.

A countertop is 18 feet long and 5 feet wide.
madam [21]

Answer:

The countertop is  8.37 square meters

Step-by-step explanation:

Let

L ----> the length of the countertop

W ----> the width of the countertop

we know that

The area of rectangle (countertop) is equal to

A=LW

we have

L=18\ ft\\W=5\ ft

Remember that

1\ ft=0.305\ m

To convert feet to meters multiply by 0.305

so

L=18\ ft=18(0.305)=5.49\ m

W=5\ ft=5(0.305)=1.525\ m

<em>Find the area in square meters</em>

A=(5.49)(1.525)

A=8.37\ m^2

Write an equation for the line that gose through the points (-2,6) and (2, 12)
arlik [135]

Answer:

y = \frac{3}{2} x + 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 2, 6 ) and (x₂, y₂ ) = (2, 12 )

m = \frac{12-6}{2-(-2)} = \frac{6}{2+2} = \frac{6}{4} = \frac{3}{2} , then

y = \frac{3}{2} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation.

Using (2, 12 ) , then

12 = 3 + c ⇒ c = 12 - 3 = 9

y = \frac{3}{2} x + 9 ← equation of line
