Answer:
-6
Step-by-step explanation:
Answer:
= 4n + 3
Step-by-step explanation:
Note there is a common difference d between consecutive terms, that is
d = 11 - 7 = 15 - 11 = 19 - 15 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 4, thus
= 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3
Answer:
174 centimeters squared
Step-by-step explanation:
2×(2×5 + 2×11 + 5×11)
= 174 centimeters squared
Sum of the angles are 180
125 + 41 + x = 180
166 + x = 180
x = 14
Step-by-step explanation:
equate the two equations
