Step-by-step explanation:
UV=(-9–(-2)),(-3–(-6))
UV=(-9+2),(-3+6)
UV=(-7,3)
I think you find the change in the x and y components. I’m not really sure
23.25 just cut the cost of the example in half
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)
