Answer:
A=6a²
Step-by-step explanation:
Lowercase a is the length of one side.
P=ma^2+ba+c, so you have
118=m35^2+35b+c
218=m45^2+45b+c
563=m55^2+55b+c so solving
I get m=49/40
b=-88
c=13579/8 so its
p=(49/40)a^2-88a+(13579/8)
they're equidistant, so distance should be equal.
distance of City centre is
distance of mall is simply $x$. (ordinate is 0, means the point is on x axis , and that's the distance from origin)
thus, $$x=7$$
Answer: 24 girls
Explanation:
