Answer:
Width= 12 yards
Length= 24 yards
Step-by-step explanation:
Perimeter of a rectangle= 2(length + width)
Let
w= width
Twice as long as it is wide
Length= 2w
Perimeter of the rectangle= 72 yards
Perimeter of a rectangle= 2(length + width)
72 = 2(2w + w)
72 = 4w + 2w
72 = 6w
Divide both sides by 6
72/6 = w
12= w
w=12
Therefore,
Width= 12 yards
Length= 2w
=2(12)
=24 yards
In this sequence, a₁ equals -1.
The difference between each term is +3, so the coefficient for n will be 3.
In the sequence, a₂ equals 2. The following equation will fit this sequence, and will be your answer:

Proof:

Answer: Rectangle
Step-by-step explanation:
Answer:
x = 1
Step-by-step explanation:
As you might guess, the zeros are symmetrical about the axis of symmetry. That is, the axis of symmetry is midway between the zeros, so will be their average value:
x = (-2 +4)/2 = 1
The axis of symmetry is x = 1.
