Definition of an equilateral triangle: A triangle with the exact same sides and angles, which is 60°
<em>5 more than twice a number:</em>
Let the number be x:
2x + 5
<em>Since it is an equilateral triangle, multiply that by 3:</em>
3(2x +5) = 6x + 15
The perimeter is (6x + 15) inches.
Answer:
the value of the expression is
Step-by-step explanation:
42
Answer:
The correct option is B.
Step-by-step explanation:
It is given that triangle A"B"C" is the image of triangle ABC after transformation.
From the given figure it is noticed that the point C lies on positive y-axis and point C" lies on negative x-axis.
It means the figure is rotated either counterclockwise 90° or clockwise 270°. The rotation rule is
The corresponding sides of image A"B"C" are smaller than the preimage ABC.
Since k<0, therefore the transformation shows the reduction. The dilation rule is
Option B is correct.
