Area of a rectangle =length*width
length=18ft=18/3=6yds
width=12ft=12/3=4yds
answer:
4x + 2y = 8 (1)
8x + 4y = -4y (2)
A) Two lines are parallel if they have the same gradient
- putting both equations into the gradient- intercept form ( y = mx + c where m is the gradient)
(1) 4x + 2y = 8
2y = 8 - 4x
y = -2x + 4
(2) 8x + 4y = -4y
<span> </span>8x = -4y - 4y
y =

y = -x
<span>
Thus the gradient of the two equations are different and as such the two lines are not parallel</span>
B) When two lines are perpendicular, the product of their gradient is -1

p = (-2) * (-1)
p = 2
<span> ∴
the two lines are not perpendicular either.</span>
Thus these lines are SKEWED LINES
Place your dot roughly around 2.23. The square root of 5 is 2.23
The correct term would be real numbers because whole numbers only belong in rational numbers. However, real numbers include BOTH ration and irrational numbers.
The answer is:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
