I’m struggling help ASAP

see explanation

Step-by-step explanation:

The n th term of an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 40 ( first row )

d = - 4 ( 4 fewer than the row below ), thus

= 40 - 4(n - 1) = 40 - 4n + 4 = 44 - 4n

That is

= 44 - 4n

(b)

a₁₀ = 44 - 4(10) = 44 - 40 = 4

There are 4 boxes on the 10 th row

b is the answer that makes most sense

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
