Plz help me T-T it’s math

a(n) = 128

Step-by-step explanation:

The formula for an arithmetic sequence is

a(n) = a1 + (n-1) d

You need to plug the numbers in to solve

a(n) = -12 + (36-1) 4

a(n) = -12 + 35 * 4

a(n) = -12 + 140

a(n) = 128

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
