To find the difference of the given expression, first step is to get rid of parenthesis. So, distribute negative sign to each terms of the second parenthesis. Hence,

(9x² + 10x + 4) - (9x² + 5x - 1)

= 9x² + 10x + 4 - 9x² - 5x + 1.

= (9x² - 9x²) +(10x - 5x) + (4 + 1) Group the like terms.

= 0 + 5x + 5 Combine the like terms.

= 5x + 5.

So, first choice is correct.

Hope this helps you!

Ostrovityanka [42]

Answer:

48.6 quart of fertilizer

Step-by-step explanation:

The directions say to use 4/5 of a quart of fertilizer for each acre of land.

Alan has two fields,

Field 1

22 1/2 acre of land

1 acre of land = 4/5 quart

22 1/2 acre of land = x

Cross Multiply

x = 22 1/2 × 4/5

x = 45/2 × 4/5

x = 18 quart of fertilizer

Field 2

38 1/4 acres of land

1 acre of land = 4/5 quart

38 1/4 acre of land = x

Cross Multiply

x = 38 1/4 × 4/5

x = 153/4 × 4/5

x = 30.6 quart of fertilizer

The total fertilizer that Alan will need for his two fields is calculated as:

18 quart of fertilizer + 30.6 quart of fertilizer

= 48.6 quart of fertilizer
