Answer:
130
Step-by-step explanation:
i think
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)
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 
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
