Answer:
A) B and C
Step-by-step explanation:
To find the perimeter, add up the lengths of all the sides.
For shape A: 16+16+1+1= 34
For shape B: 8+8+2+2= 20
For shape C: 5+5+5+5= 20
Shapes B and C both have a perimeter of 20. The answer is A, B and C.
I hope this helps!

The other answer is not correct because they are finding the area of the rectangles.
Answer:
C - f(t) = 4(t − 1)^2 + 2; the minimum height of the roller coaster is 2 meters from the ground.
Step-by-step explanation:
Here we're asked to rewrite the given equation f(t) = 4t^2 − 8t + 6 in the form f(t) = a(t - h)^2 + k (which is known as the "vertex form of the equation of a parabola.") Here (h, k) is the vertex and a is a scale factor.
Let's begin by factoring 4 out of all three terms:
f(t) = 4 [ t^2 - 2t + 6/4 ]
Next, we must "complete the square" of t^2 - 2t + 6/4; in other words, we must re-write this expression in the form (t - h)^2 + k.

I think the answer is number 3
Answer:
108 kilometers per hour = 30 meters per second
So, 108 kilometers per hour = 108 × 0.27777777777778 = 30 meters per second.
Answer:
50°
Step-by-step explanation:
The internal angles on a quadrilateral sum to 360.
So x+10+2x+x+3x=360
7x+10=360
7x=350
x=50
