For the first one (aka 7) you would write 10² wich is the same as 10×10 and so the answer is 100
For the second one (aka 8) you would write 3×3×3×3×3×3×3×3×3 and the answer is 486 square miles
At the end of the directions, it talks about parallel, perpendicular, or neither. When x=y, the lines are perpendicular and have infinite solutions. When they are parallel, there is no solution. You'll get an answer like 4=5. Neither means there is only one answer, and you will get one x and one y.
Answer:
9x-7y+28=0
Step-by-step explanation:
using formula
y-y1=m(x-x1)
y-4=9/7(x-0)
7y-28=9x
9x-7y+28=0
P=6.50*10-18.00
hope this helped!❤️
