Answer:
The length of the rectangle is 11 inch and its width is 8 inch.
Step-by-step explanation:
Given:
Rectangle
and rectangle
.
Let the width of the rectangle be 'x' inch.
Its length = '(x+3)' inch
Area of the rectangle = 
⇒
= 
Now for rectangle
its width is decreased by 1 inch and length is doubled,the area
will increased by 66 sq-inch.
So,
According to the question.
⇒ Area of rectangle
with width '(x-1)' and length '2(x+3)'='(2x+6)' .
⇒ 
Plugging the values of
in terms of
.
⇒ 
Plugging
=
into the equation.
⇒
⇒ 
⇒ 
⇒ 
Now using quadratic formula we can find the value of 'x'.
Quadratic formula, (x)=
x= -9 and x= 8
Discarding the negative value.
Our width = 'x' = 8 inches.
So the length of the rectangle = 11 inches and width of the rectangle = 8 inches.
I believe the answer is 23.52 because if u add 19.60 to 20% thats what u get

Step-by-step explanation:
Answer: y=1/4x+5
Step-by-step explanation:
Slope intercept form is
y=mx+b
where mx is the slope and b is the y-intercept.
The y-intercept is the part were the line touches the y axis, which in this case you can see is the five
To find the slope you need to use two points. I used (0,5) and (4,6).
This part is kind of tricky to explain so I kinda hope you already know this and sorry if it doesnt make sense but the slope needs to be written as rise/run which could also be reffered to as difference in y/difference in x. So basically what I did is subtract the difference in y values, which is 1 and the difference in x values, which is 4. And then I just put the difference in y value over the difference in x value
(ps I'm really sorry if im wrong-)
the tens place is the 1st six from the right
We look at the 4 and it is less than 4 so we leave the six alone
