Answer:
tgh
Step-by-step explanation:
We are given
length of rectangle is 4x-3
width of rectangle is 6x+9
we know that
Area of rectangle = length of rectangle*width of rectangle
so, we can plug value
and we get

now, we can distribute it

now, we can simplify it

...............Answer
FALSE
The standard form of the equation of a circle is

With (a, b) representing the centre and r representing the radius.
The radius of the circle in the attachment is 5, and therefore the circle has the following equation.

The length of EF is 3.8
<h3>How to solve for EF?</h3>
To do this, we make use of the following law of sines
EF/sin(D)= DE/sin(F)
So, we have:
EF/sin(75)= 3/sin(50)
This gives
EF = sin(75) * 3/sin(50)
Evaluate the product
EF = 3.8
Hence, the length of EF is 3.8
