Answer:
no
Step-by-step explanation:
For example: 4(2)-2 and 2(2-1)
6 is not equal to 2
Answer: A
Step-by-step explanation:

16+10=26
Answer:
you can use siri or google or alexa. Just say " pick 7 numbers from 1-650 "
Step-by-step explanation:
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)
