-9=-3(x+2) solve for x show steps

lianna [129]

SimplifyOkie dokie so first things first, you have to get rid of those parentheses! To do this you use the distributive property. -3(x+2) is the same thing as -3(x)+-3(2). that and you get -9=-3x-6. So you want to get x by itself to be able to find what x is, so you add 6 to both sides of the equation to get rid of the -6. So then you get -3=-3x. Then you must divide both sides by the coefficient of x, which would be -3. When you divide both sides by -3 you get -3/-3=x, which is the same thing as 1=x. Hope this helped!

The volume of a rectangular prism is found using the formula V = l · w · h, where l is the length, w is the width, and h is the

Anastaziya [24]

There are additional details to the problem that you have left out. I have found them in other resources. The tray has to be 3 centimeters high and the length is five centimeters longer than its width. The volume of the tray is 252 cubic centimeters.

With these given, we can find the equation with the width alone as the variable:

$V=lwh$
$252=(x+5)(x)(3)$
$84= x^{2} +5x$

To know if it's possible for the width to be 7.5 centimeters, we just plug this as the value of x and see if it satisfies the equation:

$84= (7.5)^{2} +5(7.5)$
$84= (7.5)^{2} +5(7.5)$
$84=93.75$

As we can see, the equation was not satisfied therefore it is NOT possible for the width to be 7.5 centimeters.
