Answer:
51
Step-by-step explanation:
12+39=51
Area of triangles: 1/2 x b x h
area of square: l x w
Triangle
1/2 x 7 x 4= 14, but there are 3 of them so 42
Square: 7 x7 = 49
49 + 42 = 91
Answer:
Step-by-step explanation:
<u>According to triangle similarity, corresponding sides have equal ratios.</u>
<u>Convert the ratio as below:</u>
- (AD - MD)/AD = AN/(AN + NG)
- (42 - 27)/42 = 20/(20 + 3x + 3)
<u>Simplify and solve for x:</u>
- 15/42 = 20/(3x + 23)
- 5/14 = 20/(3x + 23)
- 1/14 = 4/(3x + 23)
- 3x + 23 = 4*14
- 3x + 23 = 56
- 3x = 33
- x = 11
The range is all the y-coordinates, so the answer would be B.
