Answer: option C. 9,555.
Justification:
1) The summation is:
6
∑ 7(4)^ (i - 1)
i=1
2) Substitute with the values of i from 1 to 6 (note that 7 is a common factor of all the terms) =>
7 { 4^(1-1) + 4^(2-1) + 4^(3-1) + 4^(4-1) + 4^(5-1) + 4^(6-1) } =
= 7 { 4^0 + 4^1 + 4^2 + 4^3 + 4^4 + 4^5 } = 7 { 1 + 4 + 16 + 64 + 256 + 1024} =
7{1365} = 9,555.

, / 6, 8 & 10
So 3 triangles
Step-by-step explanation:
The longest side of a triangle has to be greater than the difference of the other 2 sides, and less than the sum of the other 2.
diff < long side < sum
Not equal to, less than & greater than.
Answer:
3) x=3
I only know the answer for number 3 I'm sorry lol
Step-by-step explanation:
Answer:
x=66
Step-by-step explanation:
A straight line is equal to 180 degrees so we can make the equation 180=2x-48. After this we can do 180-48=2x then we can do 132/2=x
