Therefore, f(c) = 3c+5
OPTION B is the correct answer
Answer:
The answer is 1485 m^2
Step-by-step explanation:
27 per m^2 so 27 times 55 = 1485 m^2
The answer to the math problem is 8y^12
If you expand out the brackets you get this,
(4+5i)(a+2i) = 4a + (5a)i + 8i - 10
The -10 comes from 5i * 2i.
Squaring i becomes -1.
Let's group the real stuff together,
and imaginary separately,
(4a - 10) + (5a + 8)i
For this to be purely imaginary,
the real part needs to be zero.
Therefore 4a - 10 = 0
Solve for a.
