Answer:

$d = \sqrt{205}$

Step-by-step explanation:

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

$d = \sqrt{(-8 - (-2))^2 + (7 - (-6))^2}$

$d = \sqrt{(-6)^2 + 13^2}$

$d = \sqrt{36 + 169}$

$d = \sqrt{205}$

George had one sheet of paper. He cut it into 6" x 5", and 3" x 6". What were the dimensions and total area of his original shee

Deffense [45]

Answer: $l={8}'' ,b={6}''$ , $l={6}'' ,b={8}''$

and area is $=48$ inch square

Step-by-step explanation:

area of sheet $=l\times b$

area of sheet first $={6}''\times {5}''$

$=30$ inch square

area of sheet second $={3}''\times {6}''$

$=18$ inch square

total area of both sheet $=30+18$

$=48$ inch square

area of sheet $=l\times b$

$=48$ inch square

$l={6}'' ,b={8}''$

or

$l={8}'' ,b={6}''$

perimeter of sheet

$=2\left ( l+b \right )$

$=2(6+8)$

$={28}''$

Determine the quotient, q(x), and remainder, r(x) when

Vinvika [58]

ANSWER

Quotient:

$q(x) = 4 {x}^{2} + 3x + 2$

Remainder:

$r(x) = 3x + 1$

EXPLANATION

The given functions are

$f(x) = 12 {x}^{4} + 21 {x}^{3} + 31 {x}^{2} + 21x + 9$

and

$g(x) = 3 {x}^{2} + 3x + 4$

We want to find the remainder and quotient when f(x) is divided by g(x).

We perform the long division as shown in the attachment.

The quotient is

$q(x) = 4 {x}^{2} + 3x + 2$

The remainder is

$r(x) = 3x + 1$

I not very good with slope and y intercept form. any tips ?

jeyben [28]

Step-by-step explanation:

To find the slope you use the slope formula which is y2-y2/x2-x1

And to find the y intercept you use y=mx +b. Yous substitute the slope as m and you substitute a point from the line to find b. Which is the y intercept
