Answer:

Factorized form of the given expression is (k + 2f)(k - f).

Step-by-step explanation:

The given expression is k² + kf - 2f² and we have to factorize the given expression.

k² + kf - 2f² = k² + 2kf - kf - 2f²

= k(k + 2f) - f(k + 2f)

= (k + 2f)(k - f)

So the factorized form of the expression is (k + 2f)(k - f).

Help! ASAP!!!

solniwko [45]

Answer:

7.2 units

Step-by-step explanation:

Coordinates of city A = (0, 0)

Coordinates of city B = (6, 4)

Use the distance formula to find the distance between the two cities as follows:

$AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$A(0, 0) = (x_1, y_1)$

$B(6, 4) = (x_2, y_2)$

Plug in the values into the formula

$AB = \sqrt{(6 - 0)^2 + (4 - 0)^2}$

$AB = \sqrt{(6)^2 + (4)^2}$

$AB = \sqrt{36 + 16} = \sqrt{52}$

$AB = 7.2$ (nearest tenth)

Reasoning triangle $abc$ has a perimeter of $12$ units. the vertices of the triangle are $a(x,\ 2),\ b(2,-2)$ , and $c(-1,\ 2)$

OlgaM077 [116]

hmmm let's find the distance between B and C first off.

$~~~~~~~~~~~~\textit{distance between 2 points} \\\\ B(\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\qquad C(\stackrel{x_2}{-1}~,~\stackrel{y_2}{2})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ BC=\sqrt{(~~-1 - 2~~)^2 + (~~2 - (-2)~~)^2} \implies BC=\sqrt{(-1 -2)^2 + (2 +2)^2} \\\\\\ BC=\sqrt{( -3 )^2 + ( 4 )^2} \implies BC=\sqrt{ 9 + 16 } \implies BC=\sqrt{ 25 }\implies BC=5$

hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.

A trapezoidal mural with bases 11m and 9m and height 6m needs to be painted. What is the cost of painting it if a box of paint i

Dovator [93]

Answer: The total cost to paint the mural will be $80.

First, we need to find the area of the trapezoid. The formula is one-half times the height times the sum of the bases.

0.5 x 6 (9 + 11) = 60 m^2

Each can will cover 12 m^2, so divide 60 by 12 to find that we need 5 cans.

The cost of each can is $16, so 5 x 16 = $60.
