Write and solve a quadratic equation for the situation below. Choose the answer that has both an equation that correctly models
Klio2033 [76]
Okay so the area of a rectangle x by y with a border of width b will be:

A=(x+2b)(y+2b)

A=xy+2bx+2by+4b^2  we are told that A=320, x=11, and y=15 so now we have:

320=165+22x+30x+4x^2, now I am using x as the border width...

4x^2+55x+165=320  is the equation that they listed..

...

4x^2+55x-155=0  using the quadratic formula for efficiency...

x=(-55±√5505)/8  since x>0

x≈2.399  which for some unknown (incorrect) reason they rounded to

x=2.5

So in short, your answer is a)

True or false: When a figure on a coordinate grid is translated down and to the right, the vertex with the largest y-coordinate
GuDViN [60]

Answer:

The correct option is;

This statement is true

Step-by-step explanation:

The given transformation are;

1) Vertical translation, y units down

2) Horizontal translation x units right

Therefore, the equivalent transformation is T_{(x, -y)}

Whereby the coordinates of the of the point on the preimage with the largest y-coordinates are  (a, b), we have;

The coordinate of the corresponding point on the image = (a + x, b - y)

Given that the value of b is larger than the the y-coordinates values of al the points on the preimage, therefore, the value of b - y, will be the largest of the y-coordinates values on the image
