Answer:
2000 feet.
Step-by-step explanation:
Let the length of fence need be x feet.
Then we have the equation:
2lx = 19x + 4000
21x - 19x = 4000
2x = 4000
x = 2000.
Answer:
6x+19
Step-by-step explanation:
distribute the six to get 6x+12+7
combine like terms 6x+19
move 19 to other side 6x=19
divide by 6
x=3.1666666667
Answer:
Perpendicular.
Step-by-step explanation:
For parallel lines slopes are equal.
The slope of y = x + 3 is 1 and the slope of y = -x - 5 is -1 so they are not parallel.
For perpendicular lines m1*m2 = -1 (where m1 and m2 are the slopes).
So these 2 lines are perpendicular.
<span>y= 1/2 x -7 point s are(-3,-2)
m=1/2
y-y1=m(x-x1)
y+2=1/2(x+3) parallel lines have same slope</span>
Answer:
answer is 6.3
Step-by-step explanation:
there is no way to get 6.80 from 2.25*2.80 because its answer is 6.3
