Answer:
Step-by-step explanation:
We are asked to find the measure of each exterior angle of a regular dodecagon.
We know that a regular dodecagon is a 12 sided regular polygon with each side equal.
We know that measure of each angle of n-sided regular polygon can be found using formula:
Upon substituting 
in above formula, we will get:
Therefore, the measure of each exterior angle of a regular dodecagon is 30 degrees.
Answer:
about 3/4
Step-by-step explanation:
To tell what the y value of a certain x value will be is very simple if we have a graph--you can just look at the portion of the graph where x = 6. At that point, it appears to be 3/4 ish on the y-axis
Q1. The answer is 4(2x - 3)(2x + 1)
16x² – 16x – 12 = 4 * 4x² - 4 * 4x - 4 * 3 =
= 4(4x² - 4x - 3) =
= 4(4x² + 2x - 6x - 3) =
= 4(2x * 2x + 2x - (2x * 3 + 3)) =
= 4(2x(2x + 1) - (3(2x + 1))) =
= 4((2x + 1)(2x - 3)) =
= 4(2x - 3)(2x + 1)
Q2. The answer is 3(x + 8)(x - 1)
3x² + 21x – 24 = 3 * x² + 3 * 7x - 3 * 8 =
= 3(x² + 7x - 8) =
= 3(x *x - x + 8x - 8) =
= 3((x(x - 1) + 8(x - 1)) =
= 3(x + 8)(x - 1)

Answer:
42 plants
Step-by-step explanation:
Dimensions are missing.
Suppose a right triangle has a base of length 7yards and a height of 24 yards.
As you know, Area of triangle can be determined by
Area of triangle 'A'= 1/2 x b x h = 1/2 x 7 x 24
A= 84 yards²
Now she wants 2 plants for each square yard of area
therefore, if the area is 84 yards²:
number of plants are 84/2=> 42 plants
Thus, She wants 42 plants in the garden
