3x square - 6x + 3=0

Answer: 1

Step-by-step explanation:

First you need to multiply 3 x 3 (9), because that's all 3 squared means.

Now the equation should be 9x-6x+3=0

Next we need to combine like terms. Do 9x - 6x which should give you 3x

Now your equations should be 3x+3=0

Now for the somewhat harder part...

Under the three (the one without the x) write -3 and under the zero write the same thing. the +3-3 cancels out so just put a line or something across it.

0-3= -3

so now you should have...

3x=-3 ignore the 3x, at this point it's useless in getting the answer because it would cancel out.

-3 divided by -3 is 1 because a negative (-) divided by a negative (-) equals a positive (+).

The answer should be x = 1

The length of a rectangle is five times its width. If the perimeter is at most 96 centimeters, what is the greatest possible val

Dvinal [7]

Let width be W

Then length = 5W

P=2L+2W

P< 96cm

Then the Perimeter of the rectangle is equal to

(2L+2W)< 96

2*(5W)+2W)≤96

Therefore, 2w+2⋅(5w)≤96

should be your answer

Find the inequality represented in the graph.

Digiron [165]

Answer: y > -1/2x + 2

Step-by-step explanation: first, in order to find the inequalities you should find the gradient by choosing two points from the line and you should you the formula m=y2-y1/x2-x1 to find the gradient.

Next, you should find the y-intercept in order to complete the inequality it can be easily found as the y-intercept is the place where the line crosses the y axis

Then you create your equation { y = -1/2x + 2 } and then if above the line is shaded then it is {> greater than} and if below the line is shaded then it should be {< less than}

(so you should replace the equation with the lesser or greater sign according to the way the graph is shaded)
