Reduce the fraction:<br> 7b-14b²/42b²21b

ch4aika [34]

Answer:

(1-2b)/126b^2

Step-by-step explanation:

(7b-14b^2)/(42b^2*21b)

factor out the 7b,

[7b(1-2b)]/882b^3

[7b(1-2b)]/[7b(126b^2)]

cancel out the 7b's

(1-2b)/126b^2

The vertices of a polygon are P(0,4), Q(5,4), R(5,−3) and S(0,−3). What is

andrezito [222]

Answer:

Perimeter of the polygon p = 24

Step-by-step explanation:

Step(i):-

Given the vertices of a polygon are

P(0,4) ,Q( 5,4) ,R( 5,-3) and S(0,-3)

The distance of PQ

$a = PQ = \sqrt{(4-4)^{2} +(5-0)^{2} } = \sqrt{25} =5$

The distance of QR

$b = Q R= \sqrt{(-3-4)^{2} +(5-5)^{2} } = \sqrt{49} =7$

The distance of RS

$c = RS = \sqrt{(0-5)^{2} +(-3+3)^{2} } = \sqrt{25} =5$

The distance of PS

$d = PS = \sqrt{(0-0)^{2} +(-3-4)^{2} } = \sqrt{49} =7$

<u><em>Step(ii):-</em></u>

Perimeter of the polygon

= sum of all sides of polygon

p = a+ b+ c+ d

p = 5+7+5+7

p = 24

<u><em>Final answer:-</em></u>

Perimeter of the polygon p = 24
