Answer:
5m² - 6m + 1
Step-by-step explanation:
f(x) = 5x² + 4x - 5
substituting value,
f(m-1) = 5(m-1)² + 4(m-1) - 5
so,
5(m-1)² + 4(m-1) - 5
= 5(m²-2m+1) + 4m -1 - 5
= 5m² - 10m + 5 + 4m - 4
= 5m² - 6m + 1

Answer:
D. $680
Step By Step Explanation:
100 pages are typed. Each page coast $5 to type.
100 x 5 = 500
40 pages are revised once. It costs $3 to revise a page once.
40 x 3 = 120
10 pages are revised twice. It costs $3 to revise a page once so it will cost $6 to revise it twice
10 x 6 = 60
To find the total cost we add all the amounts together
500 + 120 + 60 = 680
The final answer is $680
