I dont really feel like graphing it out but i can explain it. so lets say that you had some graph points and when you drew them together it was the shape of a circle so make a line down that circle and the rule is if that circle passes through that line you drew more than 2 times it is not a function, and if it only passes through that line once then it is a function.
Answer:
72
Step-by-step explanation:
6 x 6 x 2 = 72
41.2 cm
Step-by-step explanation:
subtract the y's and x's to get the distances
left & right sides are hypotenuses
top :
10 - (-2) = 12
bottom :
5 - (-7) = 12
left :
3 - (-4) = 7 = height
-7 -(-2) = -5 = 5 = base
pythagorean theorem
49 + 25 = 74
square root of 74 = 8.6
right :
same
perimeter :
12 + 12 + 8.6 + 8.6 = 41.2

Answer:
a. √9
Step-by-step explanation:
a. √9 = 3
b.√15 = sqrt(5*3) cannot be simplified
c. √18 = sqrt(9) sqrt(2) = 3 sqrt(2) cannot be simplified farther
d. √20= sqrt(4) sqrt(5) = 2 sqrt(5) cannot be simplified farther
a is the only answer that is a rational number
