$\\ \sf\longmapsto A=(1-4)-(2+1)$

$\\ \sf\longmapsto A=-3-3$

$\\ \sf\longmapsto A=-6$

$\\ \sf\longmapsto B=(3-\dfrac{1}{2})-(2-4)$

$\\ \sf\longmapsto B=\left(\dfrac{5}{2}\right)+2$

$\\ \sf\longmapsto B=\dfrac{5+4}{2}$

$\\ \sf\longmapsto B=\dfrac{9}{2}$

Now

$\\ \sf\longmapsto AB=-6\times \dfrac{9}{2}$

$\\ \sf\longmapsto AB=-3(9)$

$\\ \sf\longmapsto AB=-27$

BA

$\\ \sf\longmapsto \dfrac{9}{2}\times (-6)$

$\\ \sf\longmapsto 9(-3)$

$\\ \sf\longmapsto -27$

Observed:-

$\\ \sf\longmapsto AB=BA$

X subtract 9 equals 3 / 5X

Korvikt [17]

Answer:

$x=22\frac{1}{2}=22.5$

Step-by-step explanation:

$x-9=\frac{3}{5}x$

First, lets get rid of the fraction. I did this by multiplying both sides by $5$ .

$5(x-9)=5(\frac{3}{5}x)\\5x-45=\frac{5}{1} *\frac{3}{5}x\\5x-45=\frac{15}{5}x\\5x-45=3x$

We want to isolate $x$ on one side of this equation. Let's put any values with $x$ on one side of the equation, and normal integers on the other.

$2x=45$

Divide both sides by $2$ .

$x=\frac{45}{2}$

If your teacher wants you to leave your final answer as an improper fraction, your final answer is this. If they want it to be a mixed number or decimal, your final answer will be:

$x=22\frac{1}{2}=22.5$

Subtract 3x squared +7x-4 from 8x squared-6+2 your answer should be polynomial in standard form

aleksley [76]

Answer:

5x² - 13x + 6

Step-by-step explanation:

8x² - 6x + 2 - (3x² +7x -4)

Simplify the expression:

8x² - 6x + 2 - 3x² -7x + 4

Combine like terms:

5x² - 13x + 6
