A shape with eight angles and sides is called an octagon.
Answer:
2(x-5)(x+4)
Step-by-step explanation:
2x^2 − 2x − 40
Factor out a 2
2(x^2 -x -20)
What 2 numbers multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
2(x-5)(x+4)
A) y=2x
b) y=1.5x
c) Blueberries as it cost less from the strawberries because the slope of the slope of the line is less then the strawberries
(slope is what multiplies with the x value (the horizontal line) and the y (vertical line) is what the answer is, ex: y=2x then for the input (x value) 1 then the output (y value) is 2)
Trying to explain it so you also understand the concept
Not all verbal expressions can create a graph.
<span>An example of one that can is: </span>
<span>"Price is always cost plus twenty dollars" </span>
<span>this would translate into the equation: </span>
<span>P = C + 20 </span>
<span>which can be graphed on a coordinate system where y=P and x=C. </span>
The complete question is
"A 4 inch by 6 inch picture is placed in a frame that creates a uniform border of x inches around the picture. The area of the entire frame (including where the picture is placed) is equal to 55.25 square inches.
What will be the width and length of the frame?"
The width of the frame is 4+2x, and the length of the frame is 6+2x.
<h3>What is the area of the rectangle?</h3>
The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
We know that the picture is 4 inches wide and 6 inches long.
Since there is a uniform border of x inches around the picture, so we must add 2x inches to each dimension.
The area will be = (4+2x)(6+2x) = 55.25
Therefore, the width of the frame is 4+2x, and the length of the frame is 6+2x.
