Answer:
Step-by-step explanation:
(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
Answer:
She will be able to cut approximately 2 yards off and still have 1 yard.
Step-by-step explanation:
Because 3-2=1 so there would be 1 yard left.
It would be a decimal which is 3.363636363636364 and if you convert it into a fraction it is 9090909091/25000000000 so in real terms it is 3 students per computer.
