What is the first month in which Maria's amount of land exceeds Lucia's amount of land?

7th Month

Step-by-step explanation:

The number of hectares of Lucia's land grows arithmetically by 5 hectares each month.

Whereas, the number of hectares of Maria's land grows geometrically with a common ratio of 1.4 every month.

Writing this as sequence expressions:

For Lucia,

First term, a=11 hectares

Common difference, d=5

Therefore:

For Maria,

First term, a=6 hectares

Commons ratio=1.4

Next, we compute and compare the results for values of n of these two equations:

Therefore, in the seventh month, Maria's land will exceed that of Lucia.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
