1 it is true
${x}^{2} - 4 = 0 \\ {x}^{2} = + 4 \\ x = \sqrt{4} = 2$
2 it's not true
${x}^{2} = - 4$
3 it's not true
$3 {x}^{2} + 12 = 0 \\ 3 {x}^{2} = - 12 \\ {x}^{2} = \frac{ - 12}{3} = - 4 \\$
4 it's true
$4 {x}^{2} = 16 \\ {x}^{2} = \frac{16}{4} = 4 \\ x = \sqrt{4} = 2$
5- it's true
${2(x - 2)}^{2} = 0 \\ {(x - 2)}^{2} = 0 \\ x - 2 = 0 \\ x = 2$

A cruise ship has a large,

Arte-miy333 [17]

Answer:

$28.27m^2$

Step-by-step explanation:

To solve this problem, we can use the area of a circle formula as shown below:

$A=\pi r^2$

A = area

r = radius

First we need to find the radius.

The radius is half of the diameter. For this problem, the radius is going to be 3.

Now, plug the values into the equation:

$A=\pi (3^2)$

$A=28.27$

The window's area is $28.27m^2$

Can someone please tell me how to solve this and this type of questions?

Hey! So you are going to find the coordinates of P and R
P is (4,0) R is (-6,-4)
Then you can plug it into this formula: (x1-x2)^2 + (y1-y2)^2
Using P and R coordinates that’s:
(4- -6)^2 + (0- -4)^2
10^2 + 4^2
100 + 16=
116
Then you are going to find the square root
So 116 square root is 10.8 rounding to the nearest tenth
Hope this helps!
