Weegy: The simplest form of 3 8/10 is ; convert this mixed fraction to improper fraction ; 38/10 ; factor both numerator and denominator; 2(19) / 2(5) ; by elimination ; 19/5 ; therefore the lowest simplest form is 3 4/5. User: Translate into a matimatical sentence: ‘ five less than twice a number’ Weegy: Five less than twice a number is 2n - 5. User: The width of a rectangle is x inches. The length of that rectangle is 4 inches less than three times the width. If the perimeter is 40 inches, what is the length and width of this rectangle? Show all of the work using algebra. Weegy: P=2L + 2W 40=2(8) + 2(12 the L=16 and the W= 24 hope it will help you User: Find three consecutive even numbers whose sum is 42. Show all your work using algebra.

(x + 3)(x^2 + 5x – 4)
= x^3 + 5x^2 - 4x + 3x^2 + 15x - 12
= x^3 + 8x^2 + 11x - 12

x^2 + 3x + 7x + 21 = x^2 + 10x + 21 = (x + 3)(x + 7)
Confirmed by andrewpallarca [7/29/2014 3:02:41 AM]
Factor: x2 + 3x + 7x + 21 User: Factor: x2 – 1 User: Factor: 4x2 – 81y2
Weegy: 4x2 – 81y2 = (2x - 9y)(2x + 9y) User: Factor: x2 – 11x + 18 Weegy: x2 – 11x + 18 = (x-9)(x-2) (More)

the factors are (x + 3) (x + 7) not (x - 3) (x - 7)
because it will make it as x^2 - 7x - 3x + 21 which will become x^2 - 10x + 21 (see its minus not plus) whole equation goes wrong if its mistakenly involve minus instead of plus
thanks jeifunk for understanding this thing. i was continuously pointing out thing but was unable to make you understand.
I am referring to the first question. You answer is right. My apologies.
User: Factor: x2 + 3x + 7x + 21
Weegy: X2-10x+21 = (x-3)(x-7)

The answer should be positive : X2 + 10x + 21 = (x + 3)(x + 7)
its ok no problem. we are humans and mistakes mostly happens by humans.
