Answer: use the formula area of square the answer is 225
Step-by-step explanation:
Formula of area of square is A=s x s is the formula
Do the formula and the answer is 225
X+y=8 —> y=-x+8
Parallel lines have the same slope so the slope for your line is -1.
Plug in -5 as x and 8 as y into y=mx +b
8=-1(-5)+b
8=5+b
b=3
Your equation is y=-x+3
Answer:
ok so it would be square root 2
