Answer:
7.3
Step-by-step explanation:
For this question, you must use the distance formula. The distance formula is based around Pythagorean Theorem, so you will see some similarities.
Distance = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}[/tex]
X2 is 7 (X coordinate of school)
X1 is 5 (X coordinate of friend's house)
7 - 5 = 2
2^2 = 4
Y2 is 7 (Y coordinate of school)
Y1 is 0 (Y coordinate of friend's house)
7 - 0 = 7
7^2 = 49
4 + 49 = 53
[tex]\sqrt{53}[/tex] = 7.2801...
Round to the nearest tenth...
7.3
