Answer:
44
Step-by-step explanation:
Given, 3x^2 + 3y^2 = 42
=>3(x^2 + y^2) = 42 =>x^2 + y^2 = 42/3= 14
Thus,
= (x - y)^2
= x^2 + y^2 - 2xy
= (x^2 + y^2) - 2xy
= 14 - 2(-15)
= 14 + 30
= 44
Answer:

√((5-(-5))^2+((-24)-(-8))^2)=√(10^2+16^2)=√356<25
B) If the line is parallel, that means the slope is the same.
The slope for the original line is
=
.
The second form of coral line would be y = -1/4x + (any number). You could use
y = -1/4x + 3.c) Solve 12x = 24 + 3y for y.
3y = 12x - 24
y = 4x - 8
Perpendicular lines have negative reciprocal slopes... the negative reciprocal for -1/4 is 4. So
yes, the third coral structure is perpendicular to the first coral.
