Answer:
4^2 + (-7)^2
Step-by-step explanation:
The square of the distance is given by the distance formula as ...
d^2 = (x2 -x1)^2 + (y2 -y1)^2 = (3 -(-1))^2 + (-5-2)^2
= 4^2 +(-7)^2 . . . . . matches the second choice (sort of)

<em>Comment on notation</em>
Clearly, you understand the use of the caret (^) to signify exponentiation. The number 42 is very different from the value of 4^2 = 16. A caret is required.
96. (3+1+2 =6 then 8x2 =16 for each individual earring, then the total number of needs per earring by the total number of earrings is 6x16 which equals 96)
It seems that you have missed few parts of the question.
I searched that question on internet and got the complete question as follows:
Which term does not belong with the other three: lines, segments, planes, and rays?
Answer:
Line, segments and rays all are 1-dimensional quantity like they move in just one direction. While plane is a 2-dimensional quantity like it has length and breadth.
In that case term "plane" doesn't belong with the other three.
Hence final answer is "plane".
Step-by-step explanation:
0.75 yard = 1 costume
1 yard = 1/0.75 =4/3 costume
6 yards = 4/3 × 6 = 8 costumes
if you wanna check,
8 costumes = 6 yards
1 costume = 6/ 8
= 3/4 (0.75) yard
