Answer:

81 mm^2.

Step-by-step explanation:

A square has 4 equal sides so each side = 36/4 = 9 millmeters long.

The area = 9^2

= 81 mm^2.

Answer:

Area is 81 mm^2

Step-by-step explanation:

A square has 4 equal sides.

let x be a side. so 4x=36

x =9

to find the area, multiply 9*9

=81

Divide 14 by 25. Then you should get a decimal number. take the decimal number and multiply by 100 and done!

I need help thanks.

melomori [17]

If this shape is trapezium
m (<D) = m (<C)
since AB parallel to CD
m (<C) + m (<A) = 180°
m (<C) = 180 - 125 = 55°
m (<D) = 55°
mark me as brainlest, please

Find the inverse function of y=(x-2)^2 + 3. please show steps

Lunna [17]

Answer:

$f^{-1}(x)=2\pm\sqrt{x-3}$

Step-by-step explanation:

we have

$y=(x-2)^2+3$

step 1

Exchange the variables (x for y and y for x)

$x=(y-2)^2+3$

Isolate the variable y

step 2

$x=(y-2)^2+3$

subtract 3 both sides

$(y-2)^2=x-3$

step 3

square root both sides

$y-2=\pm\sqrt{x-3}$

step 4

Adds 2 both sides

$y=2\pm\sqrt{x-3}$

step 5

Let

$f^{-1}(x)=y$

$f^{-1}(x)=2\pm\sqrt{x-3}$
