Answer:
17
Step-by-step explanation:
Assuming the field is a rectangle, the perimeter is found through the equation:

Since we know the perimeter and width, we can substitute and solve for the length.

Using the length and width, we can find the area.

The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.

Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.
Slimination
multiply first equaiton by 2
2x+6y=10
add to second equiaotn
2x-2x+6y-6y=10-10
0=0
this is true so therfor they are the same equaiton
so solve
x+3y=5
3y=-x+5
y=-1/3x+5/3
subsituter values for x and get valuse for y
if x=2 then y=1
Answer:
80
Step-by-step explanation:
18^2 + 80^2 = 82
324 + 160 = c^2
Answer:
B
Step-by-step explanation:
Since its changing the y, we now it has to be outside the x. So its not A or D. Since it moves up, its a plus. This means its not c, so it has to be B.
