x=4
Answer:
Step-by-step explanation:
41 = 12d - 7
Adding 7 to both sides
41+7 = 12d
48 = 12 d
Dividing both sides by 12
4 = d
OR
d = 4
Answer:
Not similar

When simplified, these two ratios are not equal. These triangles are not similar.
Answer:
Option 2 and 4
Step-by-step explanation:
Area of the big rectangle to fit small ones:
Area of small rectangles:
- A= 11*7=77
- B=2*11=22
- C=6*6=36
- D=6*5=30
- E=13*4=52
Now, the answer options:
- 3E+2B= 3*52+2*22= 200 > 165 ⇒ no
- A+B+C+D= 77+22+36+30= 165 ⇒ yes
- 2C+2D+2B= 2(36+30+22)=176 > 165 ⇒ no
- A+4B= 77+4*22= 165 ⇒ yes
- E+C+D+3B= 52+36+30+22= 140 < 165 ⇒ no
