Answer:
a) Perimeter of old garden=6w+8
b) A = 2W^2+4W
Step-by-step explanation:
old Area = length * width
= L * W
the old perimeter = half of the new one, so it is 6w+8
the old perimeter has to equal 2L + 2W
2L+2W=6W+8
2L=4W+8
L=2W+4
Area=L*W
so
A=(2W+4)(W)
=2W^2+4W
Answer:
C) Tangent only
Step-by-step explanation:
In quadrant III Tangent (& cotangent as well) only is positive.
Answer:
y=-2/5x-2
Step-by-step explanation:
First, you put x to the other side of the equation so you get y alone, getting the equation of -5y=-2x+10. In order to just have y on one side, you need to divide the whole equation by -5. This leads to the final answer of y=-2/5x-2.
The place value of the 3 is that the 3 is in the tenths place.
