Davis's claim was incorrect because a rectangle sometimes only have 2 congruent sides. Drawing a rectangle, the length/width would be longer than their length/width. Unless it is a square, it counts as correct as a square can be counted as a rectangle and a rectangle can not be counted as a square but anyways, congruent means equal sides. The rectangle, mostly drawn, only has two long sizes and two short sides, both opposides are equal. Hence, the claim Davis said is incorrect.

Question: x-10&lt;6-5x<br><br> is it <br><br> x&lt;8/3<br><br> OR<br><br> x&lt;-8/3<br><br> help ;-;
Montano1993 [528]

You need to isolate/get x by itself in the inequality:

x - 10 < 6 - 5x           Add 5x on both sides

x + 5x - 10 < 6 - 5x + 5x

6x - 10 < 6              Add 10 on both sides

6x - 10 + 10 < 6 + 10

6x < 16          Divide 6 on both sides to get x by itself

x     Simplify the fraction

x          So the 1st option

What are the values of x in this equation?
NNADVOKAT [17]

Answer:

A. x = 0, x = -3, x = 2, and x = -2

Step-by-step explanation:

x^{4} +12x=4x^{2} +3x^{3}

by moving the terms on the left side to the right side

x^{4} -3x^{3} -4x^{2} +12x = 0

factor an x^{3} from x^{4} -3x^{3}

and factor - 4x from -4x^{2} +12x

the equation becomes :

x^{3} (x - 3  )-4x  (x - 3) = 0

take (x - 3)  as  a common factor the equation becomes :

(x-3)(x^{3}-4x  ) = 0

thus

x - 3 = 0⇒x = 3

and

x^{3} - 4x = 0 by factoring an x we get :

x(x^{2}-4 ) =0 ⇒ x = 0 and x^{2} - 4 = 0

x^{2} - 4 =0⇒x = 2 and x = -2

Thus

the values are :

x = 0, x = -3, x = 2, and x = -2
