For which inequality would x = 8 not be a solution?

Naya [18.7K]

Put the value of x to the inequality:

$4x+3 > 0\\L=4(8)+3=32+3=35;\qquad R=0;\qquad L > R\ CORRECT\\\\9x-5 < 100\\L=5(8)-5=40-5=35;\qquad R=100;\qquad 35 < 100\ CORRECT\\\\x+4\leq10\\L=8+4=12;\qquad R=10;\qquad 12 > 10\ INCORECT (\leq)\\\\72\div x\geq4\\L=72\div 8=9;\qquad R=4;\qquad 9\geq4\ CORRECT$

6x + 8 = 2(3x + 4)<br> what is the step by step answer to this question

stepladder [879]

Answer:

The given expression has INFINITE NUMBER OF SOLUTIONS.

Step-by-step explanation:

Here, the given expression is:

6 x + 8 = 2(3 x + 4)

Now, by <u>DISTRIBUTIVE PROPERTY:</u>

A (B+ C) =AB + AC

Now, simplifying the given expression, we get

6 x + 8 = 2(3 x + 4) ⇒ 6 x + 8 = 2(3 x) + 2( 4)

or, 6x + 8 = 6x + 8

or 6x - 6x = 8 - 8

⇒ 0 = 0

Hence the given expression has INFINITE NUMBER OF SOLUTIONS.

A rectangle with positive are has length represented by the expression 3x^2+5x-8 and width by 2x^2 +6x write an expression in te

Nata [24]

Answer:

$c=10x^2+22x-16\\A=6x^4+28x^3+14x^2-48x$

Step-by-step explanation:

Given

Length is $l=3x^2+5x-8$

Width is $w=2x^2+6x$

Perimeter of the rectangle is the sum of the sides

$\Rightarrow c=2(3x^2+5x-8+2x^2+6x)\\\Rightarrow c=2(5x^2+11x-8)\\\Rightarrow c=10x^2+22x-16$

Area is given by

$\Rightarrow A=(3x^2+5x-8)(2x^2+6x)\\\Rightarrow A=6x^4+18x^3+10x^3+30x^2-16x^2-48x\\\Rightarrow A=6x^4+28x^3+14x^2-48x$
