Answer:
370 millimeters of compound B is needed for 666 millimeters of solution.
Step-by-step explanation:
Given that:
4 millimeters of compound A are used for every 5 millimeters of compound B.
The scientist wants to make 666 millimeters of solution.
Let,
x be the multiplier number of the compounds in the solution.
Then,
4x + 5x = 666
9x = 666
Dividing both sides by 9
Millimeters of compound B = 5x = 5(74) = 370 millimeters
Hence,
370 millimeters of compound B is needed for 666 millimeters of solution.
(A) f(a + 2) = a² - 16
substitute x = a + 2 into f(x)
f(a + 2) = (a + 2)² - 4(a + 2) - 12
= a² + 4a + 4 - 4a - 8 - 12
= a² - 16
(B ) f(a + h) = a² + 2ah + h² - 4a - 4h - 12
substitute x = a + h into f(x)
f(a + h) = a² + 2ah + h² - 4a - 4h - 12
