Answer:
change f(x) to 0 than 7*2x=14x
0=14x-28x+21
0=-14x+21
-21=-14x
x=3/2
Answer: I think it is b
Step-by-step explanation:
law of demand hope i helped u
We know that
<span>applying the Pythagorean theorem
c</span>²=a²+b²
c is the <span>length of the diagonal
a=100 yd
b=130 yd
c</span>²=100²+130²-------> c²=26900---------> c=√26900 units----> c=10√269 units
the answer is
the length of the diagonal is 10√269 units or 164.012 units
C) $154 because if you add 25+89+40 that’s what you get. Hope this helps!
