Answer:

x^2-x-12

Step-by-step explanation:

You can use the formula of FOIL, you go to each factor in the parenthesis and multiply by the other factors, the inside will first be x^2 then the middles will be 3x and -4x and the outside will be -12 then you simplify by combining like terms making the middle -x.

A farmer has a soybean field with an area of 55 square meters and a cornfield with an area of 58 square meters. he also has a wh

dexar [7]

A farmer has order the fields from least area to greatest area is,

Soybean field < Cornfield < Wheat field.

Based on the given conditions,

A farmer has a soybean field with an area = 55 square meters

A farmer has a corn field with an area = 58 square meters

He also has a wheat field that is 52 times the size of the soybean field.

So,

We can write,

52 times the size of the soybean field.

That means,

= 55 * 52

Calculate the product or quotient,

= 2860

Wheat field = 2860

Hence,

Soybean field = 55

Cornfield = 58

Wheat field = 2860

Soybean field < Cornfield < Wheat field

Therefore,

A farmer has order the fields from least area to greatest area is,

Soybean field < Cornfield < Wheat field.

How do you calculate this

Alexxx [7]

Answer:

y = - 2x - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line

m = $\frac{-1-1}{0-(-1)}$ = $\frac{-2}{0+1}$ = $\frac{-2}{1}$ = - 2

the line crosses the y- axis at (0, - 1 ) ⇒ c = - 1

y = - 2x - 1 ← equation of line
