Answer:

d = √5 ≈ 2.24

Step-by-step explanation:

B is located at (1, 3) and B' is located at (3, 4)

Distance formula:

[tex] d = \sqrt{(xB' - xB)^2 + (yB' - yB)^2}[\tex]

replacing with the coordinates of the points:

[tex] d = \sqrt{(3 - 1)^2 + (4 - 3)^2}[\tex]

[tex] d = \sqrt{4 + 1}[\tex]

d = √5 ≈ 2.24

The sum of -4 and 5 times a number is multiplied by 3. The result is 212 less than 7 times the number. What is the number?

lorasvet [3.4K]

Answer:

104

Step-by-step explanation:

First, put the word equation into a numerical equation.

-4+5x=7x-212 This is our equation

-4=2x-212 I subtracted 5x from both sides

208=2x I added 212 to both sides

104=x I divided both sides by 2

Fiesta28 [93]

Answer:

The dimensions are $16$ ft by $32$ ft

The quadratic equation is $W^{2}-256=0$

Step-by-step explanation:

we know that

the area of rectangle is equal to

$A=W*L$

where

L is the length side of rectangle

W is the width side of rectangle

in this problem

we have

$A=512\ ft^{2}$

so

$512=L*W$ -----> equation A

$L=2W$ ------> equation B

substitute equation B in equation A

$512=(2W)*W \\ 512=2W^{2} \\2W^{2}-512=0\\W^{2}-256=0$

$W=\sqrt{256}=16\ ft$

Find the value of L

$L=2W-----> L=2*16=32\ ft$

Find the area of a rectangle that has the length of 2x-3 and the width of x .Someone painted an interior area of the rectangle a

Svet_ta [14]

Answer:

The area that was not painted is $(2x^{2}-6x+6)\ units^{2}$

Step-by-step explanation:

step 1

Find the area of the rectangle

we know that

The area of a rectangle is equal to

$A=LW$

In this problem we have

$L=2x-3$

$W=x$

substitute

$A=(2x-3)x\\A=(2x^{2}-3x)\ units^{2}$

step 2

Find the area that was painted

$A=(3)(x-2)\\A=(3x-6)\ units^{2}$

step 3

Find the area that was not painted

Subtract the area that was painted from the total area of rectangle

so

$A=(2x^{2}-3x)-(3x-6)=(2x^{2}-6x+6)\ units^{2}$
