Multiply: (3x + 7)(5x2 − 3x + 6) a) 15x3 + 26x2 − 39x + 42 b) 15x3 + 26x2 + 3x + 42 c) 15x3 − 44x2 − 3x + 42 d) 15x3 + 26x2 − 3x + 42

Step-by-step explanation:

Multiply

To multiply two parenthesis , we first multiply 3x inside the second parenthesis and then we multiply 7 inside the second parenthesis

Now multiply 7 inside the second parenthesis

Now we add both the answers we got

Lets combine like terms

the answer is simply just 6n add the two together as they have an n

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.
