Answer:
(x) = x + 7
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject, that is
y = x - 7 ( add 7 to both sides )
y + 7 = x
change y back into terms of x, then
(x) = x + 7
Answer: B
Step-by-step explanation: Since you know the number is not apart of the solution, the circle will definitely be open. But the circle is open so, it's apart of the problem
Begin by using the cosine rule to find the unknown side.
Where a- unknown side, b is 12, c is 16 and angle in between is 108°
The cosine rule...
a² = b² + c² - 2bc cosA
= 12² + 16² - (2×12×16 cos108°)
= 518.655076
Taking the positive
square root...
a = 22.774
a = 22.8 cm nearest tenth
