Answer:
About 8.6
Step-by-step explanation:
d=(x2-x1)^2+(y2-y1)^2
8=x1 8=y1 3=x2 1=y2
(3-8)^2+(1-8)^2
(-5)^2+(-7)^2
25+49
74
take the square root and you get about 8.6
Use the distributive property.
3*2a - 3*b = 6a - 3b.
First, find a common denominator.
12 will work.
3/4 becomes 9/12, because 4x3=12, and 3x3=9
2/12 stays the same, because the denominator is already 12.
Now, add the two together.
9/12+2/12=11/12
The finished pipe will be 11/12 ft. long. your welcome enjoy :D
