Answer: Length: 21 cm Width: 7 cm
Step-by-step explanation:So, two of the sides are 3 units long, and two of the sides are 1 unit long. The total number of units in the perimeter of the rectangle is 8.
56cm / 8units = 7cm/unit
So, the length of the rectangle is 7cm/unit x 3 units, or 21 cm.
The width of the rectangle 1/3 of the length, or 7cm.
Length: 21 cm
Width: 7 cm

Answer:
<h2>f(x) = -x² + 2x + 4</h2>
Step-by-step explanation:
We have quadratic functions f(x) = ax² + bx + c.
c - y-intercept
If a > 0, then a parabola opens up and has a minimum in a vertex.
If a < 0, then a parabola opens down and has a maximum in a vertex.
The function has maximum and y-intercept of 4:
a < 0 and c = 4
