27.47 should be the correct answer!
Answer: C. 4
Step-by-step explanation:
First, we can prime factorize 52.
52 = 2^2 * 13
13 is not a square number, but 4 is a square number because it equals 2 squared.
Therefore, the correct answer is C. 4
To get a perpendicular line, your slopes will equal -1 when multiplied...this means if we multiply - 4 x (1/4), we get out slope to use for the next step.
Y - Y1 = M(X - X1) passes through (-2, 7)
Y - 7 = 1/4(X - (-2))
Y - 7 = 1/4(X + 2)
Y - 7 = 1/4X + 1/2
+7 + 7
Y = 1/4X + 7.5
