Answer:
3x -y = 6
Step-by-step explanation:
When the equation of a line is given in the form ax+by=c, the perpendicular line through point (h, k) will be ...
bx -ay = bh -ak
Here, we have a=1, b=3, h=1, k=-3, so the line is ...
3x -y = 3(1) -(1(-3))
3x -y = 6
Answer: 659 13/18 yd^2 or 659.7yd^2 ^ =squared
Step-by-step explanation:
This is the answer because you have 6 sides of this prism. That means 3 sides are parallel to the sides across from them. So, 12 1/2 yd by 8 1/3 yd is 104 1/6, then multiply by 2. That equals 208 1/3. Then, 10 5/6 yd by 8 1/3 yd is 90 5/18. then times by 2. That equals 180 5/9. Next, 10 5/6yd by 12 1/2 is 135 and 5/12. then times by 2 and that is 270 5/6yd.
add 208 1/3 + 180 5/9 + 270 5/6
659 13/18 yd^2
It actually equals-42.50 i believe
