The correct option is a.

Step-by-step explanation:

The given equation is

Simplify the left hand side of the equation.

Using distributive property.

The correct answer is 1+3i.

He did not apply the distributive property correctly for 8(1+2i).

His calculation is shown below.

Therefore the correct option is a.

g

step-by-step explanation:

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.
