Answer:

The area of the garden is 9 km²

Step-by-step explanation:

If the garden is a square, that means that it's side length is one fourth of the total perimeter, giving us a length and width of 3km

That means that it's area is 3km × 3km, or 9km²

144 km because all sides of a square are equal and length times breadth is the area

miv72 [106K]

Answer:

Step-by-step explanation:

x³-6x²+11x-6

put x=1

1³-6×1²+11×1-6=1-6=11-6=0

by synthetic division

1| 1 -6 11 -6

| 1 -5 6

|----------------

| 1 -5 6 |0

x²-5x+6=0

x²-2x-3x+6=0

x(x-2)-3(x-2)=0

(x-2)(x-3)=0

x=1

x-1=0

so x³-6x²+11x-6=(x-1)(x-2)(x-3)

Abe real estate is developing 15 solar homes per states. If the cost of each home is estimated at 80,000 what’s the projected co

Soloha48 [4]

Answer:

the Total cost= 1,200,000*number of states

Step-by-step explanation:

Given the cost of each home is $80,000

The number of homes per state are 15

The Total cost of the project is = (Total number of houses per state) * (cost of each house) * (the number of states).

Therefore the total cost =15*80000*Number of states.=1,200,000*number of states

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 )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

Using (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 6)

m = $\frac{6-0}{-3-0}$ = $\frac{6}{-3}$ = - 2

Since the line passes through the origin (0, 0) then y- intercept is 0

y = - 2x ← equation of line

let (x₁, y₁ ) = (6, 0) and (x₂, y₂ ) = (0, 3)

m = $\frac{3-0}{0-6}$ = $\frac{3}{-6}$ = - $\frac{1}{2}$

note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = - $\frac{1}{2}$ x + 3 ← equation of line

let (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (-2, - 3)

m = $\frac{-3-3}{-2-0}$ = $\frac{-6}{-2}$ = 3

note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = 3x + 3 ← equation of line
