Answer: The value of x is 155/79.
Step-by-step explanation:
13(6x -5 )-x= 13 -2(x +1)
78x - 65- x = 13 -2x -2
77x -65 = 11-2x
79x -65 =11
79x =76
x = 76/79 76/ 79 + 1/1 = 155/79
Answer:
B) 44
Step-by-step explanation:
Let's start with the triangles. Normally, when dealing with triangles, you would use the formula (B*H*1/2), but since there's two identical triangles, we can just do (B*H) and get the area for both:
2.5*5.5=<u>13.75</u>
Then to solve for the square, it is also (B*H):
5.5*5.5=<u>30.25</u>
At this point, to solve for the total area, you just add the areas together:
13.75+30.25=<u>44</u>

A.32 it’s not very complicated you just have to find the value of A and B then multiply them together
<u>Answer
</u>
Option A) 17cm
<u>Explanation
</u>
Polygon R and polygon S are similar. This means the polygon R and S have equal number of sides.
Step 1 : Find the number of sides of polygon S
The perimeter of polygon S is 64 cm. If one side of polygon S is 8 cm
Therefore, Number of sides of polygon S = 64/8 = 8 sides
and number of sides of polygon R = 8 side
Step 2 : Find the number of sides of polygon R
The perimeter of polygon R is 136 cm,
Number of sides of polygon R = 136/8 = 17 cm
Therefore side length of polygon R = 17 cm
