Use the point-slope formula:
y+3 = (-4)(x+8)
Answer:
um15
Step-by-step explanation:
when it add and subtract is 15
diagonal = 9√2 ≈ 12.73
the diagonal splits the square into 2 right triangles with the hypotenuse being the diagonal of the square
using Pythagoras' identity
d = √(9² + 9²) = √162 = 9√2 ≈ 12.73 ( to 2 dec. places )
