Answer:
es 0.225 ... I believe so
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:
X should be 120 degrees cause opposite angles are always equal
6/100*5400
324
5400-324
5076 final answer
No she is not correct, because the absolute value of a number is its distance from zero on a number line. Therefore, you would take a number, say -1. The absolute value of this number is 1. So, add 1 and you would get 2. If I'm correct, 2 is not equal to zero. I hope this helps you out! ;)
