An equilateral triangle has 3 equal sides. Since one side is 14 cm, then all sides are 14 cm. You multiply 4 by 3 and you get your answer.
14*3=42. The perimeter is 42cm.
Answer:
320cm³ (option C)
Step-by-step explanation:

Volume of bird house = volume of a cuboid + volume of a triangular prism
Volume of a cuboid = length × breadth × height
= 8cm × 5cm × 6cm = 240cm³
Volume of triangular prism = ½ base ×height ×length
= ½ × 8×4×5 = 80cm³
Volume of bird house = 240+80
Volume of bird house = 320cm³
Amount of birdseed that will it take to fill the birdhouse = Volume of bird house = 320cm³

Step-by-step explanation:
The question presumes you have access to a computer algebra system. The one I have access to provided the output in the attachment. The list at the bottom is the list of the first four derivatives of f(x).
__
The derivatives alternate signs, so (-1)^k will be a factor.
The numerators start at 17 and increase by increasing factors: 2, 3, 4, indicating k! will be a factor.
The denominators have a degree that is k+1.
Putting these observations together, we can write an expression for the k-th derivative of f(x):

Answer:
Correct option is
B
90
∘
,90

,90

Let AB and CD be two lines Intersecting at O, such that, ∠AOD=90
∘
Now, ∠AOD=∠COB=90
∘
(Vertically opposite angles)
⟹∠AOD+∠DOB=180
o
(Angles on a straight line)
⟹90+∠DOB=180
o
∠DOB=90
∘
∠DOB=∠AOC=90
∘
(Vertically opposite angles)
Thus, all angles are 90
