I think it’s B
Hope it’s correct
The ratio (red to blue) of the perimeters of the similar triangles is 12:7
Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.
Perimeter of a triangle = s1 + s2 + s3
For the red triangle;
Perimeter of the red triangle = 12 + 12 + 12
Perimeter of the red triangle = 36
For the blue triangle:
Perimeter of the blue triangle = 7 + 7 + 7
Perimeter of the blue triangle = 21
Taking the ratio of their perimeters;
Ratio of red to blue = 36:21 = 12:7
Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7

Answer:
its b
Explanation:
because i just took the test baddies
P = 2x+2(450-x)=900
A = x(450 - x)
A = x(450 - x)
-x² + 450x = A
-x² +450x = A
A is going to be maximum, when x is a vertex.
-(x² - 450x) = A
-(x² - 2*225x+225²) - 225² =A
-(x-225)² -225² = A
Vertex when x=225
Largest are 225(450-225) = 225² = 50625 ft²
The square has a largest area.
The throws made by the dart thrower shows that the person is both accurate and precise.
Accuracy is a measure of how close an obtained value is to the actual value. Hence, since the dart is close to the center of the target. Then it is accurate.
Precision describes how a series of obtained values are close to one other. Since the five darts are position of the five darts are close to one another, then the throw is precise .
Therefore, the person who threw the darts is both precise and accurate.
