A. x <= -12
<u>Explanation:</u>
-3x >= 36
-x >= 36/ 3
-x > = 12
x < = -12
When the negative sign is shifted then the greater than equal to sign reverses to less than equal to.
Therefore, x <= -12
Explanation:
There are many versions of the taxonomy diagram for quadrilaterals. The details depend on the particulars of the definitions you use. Here, we'll say a parallelogram is a subset of trapezoids. Not all authors would agree.
(2) kite -- two pairs of adjacent same-length sides
(3) trapezoid -- (at least one) pair of parallel opposite sides
(4) parallelogram -- opposite sides are parallel
(5) rhombus -- all sides the same length (and opposite sides parallel)
(6) rectangle -- parallel opposite sides and right angles
(7) square -- same-length parallel opposite sides and right angles
To find A' they used the rule of multiplication, which is:
the derivative of a product of two terms is the first term times the derivative of the second term plus the second term times the derivative of the first.
To find b' they just isolated b'
