Help please can't figure this out!!
Which value for x makes the open sentence true?
10 • 8 – 3x + x( to the 2 power)≥ x( to the 3 power)+ x( to the 2 power)

A.6
B.4
C.5
D.7

Answer 1

Ekk you question is messy.
\[ 10\times 8 – 3x + x^2≥ x^3+ x^2 \]
Okay there much better.
Now lets break down this question.
This symbol: '≥' means greater than or equal to.
So:
\[(10\times 8 – 3x + x^2)≥(x^3+ x^2)\]
This \(10\times 8 – 3x + x^2\) side should be greater than or equal to this side \(x^3+ x^2\).
Plug in the values from your multiple choice answers till you find the value that fits the statement correctly.
