<span>==> 6(15+x) = 120
==> 15+x = 20
==> x = 5.

The area of the window is 8
.
<h3>What is the area?</h3>
An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely cover the surface of a closed figure.
The word "area" refers to a free space. The length and width of a form are used to compute its area.
Any shape's area can be calculated by counting how many unit squares will fit inside of it.
According to the question,
Length of window=2m
Width of window=4m
Area of window=Length*Width
=2*4
=8

Answer: A) I would expect the data to be positively correlated
Step-by-step explanation: Taller people have been shown to have bigger feet. It's how humans are engineered. Your feet have to support your entire body while also providing balance. Larger feet help taller people keep their balance because the pressure is distributed among a larger surface. Sure some people may have smaller feet even though they're tall, but that doesn't mean a majority of tall people have small feet.
The solution of
are 1 + 2i and 1 – 2i
<u>Solution:</u>
Given, equation is 
We have to find the roots of the given quadratic equation
Now, let us use the quadratic formula
--- (1)
<em><u>Let us determine the nature of roots:</u></em>
Here in
a = 1 ; b = -2 ; c = 5

Since
, the roots obtained will be complex conjugates.
Now plug in values in eqn 1, we get,

On solving we get,



we know that square root of -1 is "i" which is a complex number

Hence, the roots of the given quadratic equation are 1 + 2i and 1 – 2i
Y would equal 12 if x were to equal 4. You can think of it as a proportion.
