Answer:
b squared + 20b+ 100
Step-by-step explanation:
multiply Using the FOIL method
first inner outer last
so
b times b = b squared
10 times b equals 10b
b times 10 equals 10b (again)
10 times 10 equals 100
add up all the answers to get the final answer
b squared + 20b+ 100
Answer: THanks
Step-by-step explanation:
Solution :
Given that :
The radius of circle A = 6 cm
The radius of circle C = 4 cm
In circle A

The length of arc EF = 

= 14.653 cm
In circle C

The length of arc GH = 

= 9.769 cm
Therefore,
The length of EF is 14.653 cm
The length of GH is 9.769 cm
The length of EF is 1.5 times the length of GH
i.e. 14.653 = 1.5 x 9.769
14.653 = 14.653
Hence proved.
Answer:
x= 8
Step-by-step explanation:
17x + 3 = 139
17x = 136
x = 8
6 1/2 ÷ 2 3/4
6 1/2 × 2 4/3
6×2 = 12 , 1/2 × 4/3 = 4/6 = 2/3
Answer = 12 2/3
