Answer: Jessica wants 120 plants in her garden.
Explanation:
Lets find the area of the triangle first:
Tip: the formula can be base x height divided by 2 so you cant get confised about 1/2bh.
Any side of the triangle can be a base, once u find a base, there will always be one corresponding height.
In this case, the base is 12 feet
And the height is 5 feet because that side is perpendicular/corresponding to the base, meaning that the side connects to the base in a 90 degree angle.
So we have this:
12 x 5/2 = 30
The area of the triangle is 30 square feet.
Now, if Jessica wants 4 plants for each square foot of area, we do this:
4 x 30 = 120

Answer: 2.25
Explanation:
Let the width be x
Length = 3x
Perimeter of frame = 18
2(l + w) = 18
2(3x + x) = 18
2(4x) = 18
8x = 18
x = 18/8
x = 2.25 feet
Reflected over the x axis and rotated 180° is your answer
First, note that the horizontal line is the x- axis, and that the figure is reflected over the x- axis.
Next, note that the placement of each point is not exactly identical. Instead, it is flipped. This means that the side is rotated 180°
hope this helps
A suitable calculator can row-reduce the augmented matrix.
