(x+y)^2=x^2+y^2+2xy=73+2*24=73+48=121
⇒ (x+y)^2=121
Answer:
area of triangle : 1/2 x length x widht
Answer:
y=3x-21
Step-by-step explanation:
a line is parallel if the slopes of the lines are the same
so that means that out line should look something like this
y=3x+b
then, we use our point given to find b
-3=18+b
b=-21
the equation of out line is y=3x-21
