The equation that can be ued to solve for the width of the rectangular frame is 2x² + 14x - 40 = 0.
<h3>What is the equation that can be used to solve for the width?</h3>
A rectangle is a 2-dimensional quadrilateral with four right angles.
Area of a rectangle = length x width
(2x + 4) x (2x + 10) = 120
Expand the brackets
4x² + 20x + 8x + 40 = 120
Add similar terms
4x² +28x + 40 = 120
4x² +28x - 80 = 0
Divide through by 2
2x² + 14x - 40 = 0

Answer:
x= 4
y= 9
so in that case (x,y) would be (4,9)
then you go down to the x axis and go to 4.
then you go up 9 and that is your first point
same thing for the rest of them so it would be (6,3)
(1,3)
(8,7)
(8,9)
Answer:
The y-intercept is -15.
Step-by-step explanation:
y - 5 = 5(x - 4) is our equation in point-slope form.
point slope form is = y - y1 = m( x - x1)
So, we know that the slope is 5 and one point is (4, 5)
We can use this point and the slope to find the y -intercept.
y = mx + b is slope intercept form.
Let's input the values we know to find the y-intercept.
5 = 5(4) + b
5 = 20 + b
-15 = b
The y-intercept is -15.
Answer:
A is correct
Step-by-step explanation:
because the sequence is the 4 and 4
-7 + 4= -3
-3 + 4= 1
1 + 4= 5
