Simplify the expression to a polynomial in standard form: (x + 1)(3x2 – 10x + 8)
WHAT IS THIS???

3x³ - 7x² - 2x + 8

Step-by-step explanation:

(x + 1)(3x² - 10x + 8)

Each term in the second factor is multiplied by each term in the first factor, that is

x(3x² - 10x + 8) + 1 (3x² - 10x + 8) ← distribute parenthesis

= 3x³ - 10x² + 8x + 3x² - 10x + 8 ← collect like terms

= 3x³ - 7x² - 2x + 8

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

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.
