3x - 20 + 3x + 5 = 111
Combine like terms
6x - 15 = 111
Add 15 to each side.
Evaluate
6x = 126
x = 21
Plug x back into the equation for angle EFG.
EFG = 3x -20
3(21) - 20
EFG = 43 degrees
The answer is 6(3) equal 18
Answer:
18
Step-by-step explanation:
The value of n = 1 , 2 , 3. Find the first 3 term and add them.
3*1 + 3*2 + 3*3 = 3 + 6 + 9
= 18
36:64
Divide each by 4 to get it in simplest form
You get 9:16 as your answer
Solving the area of the circle
A = π × 2^2
A = 12.57
halve
/2 = 6.29
area of the square = 4*4
16
subtract area of half circle from area of square
16 - 6.29 = 9.71
