Answer:

A) 3(x+6)

Step-by-step explanation:

Given,

The area of the model = (6x+18)

If the dimensions of the model are, x unit × y unit,

Then,

xy = 6x + 18

If x = 3, y = x + 6

3(x+6) = 3x + 18 ( by distributive property )

∴ Option A doesn't represent the dimensions of the model,

If x = 6, y = x + 3

6(x+3) = 6x + 18

∴ Option B represents the dimensions of the model,

If x = 0.5, y = 12x+36

0.5(12x+36) = 6x + 18

∴ Option C represents the dimensions of the model,

If x = 0.25, y = 24x + 72

0.25(24x+72) = 6x+18

∴ Option D represents the dimensions of the model,

Someone please help me thank you

Answer:

x = - 1

Step-by-step explanation:

Given

4x = x^2 - 5 Transfer 4x to the right side.

Solution

x^2 - 4x - 5 = 0 Factor

(x - 5)(x + 1)

You want the negative solution. That means that the middle sign must be plus.

x + 1 = 0 Subtract 10 from both sides

x = - 1 Ten on the left disappears by the subtraction process.

Is that correct?

4x = x^2 - 5

x = - 10

4*(-1) = (-1)^2 - 5

-4 = ? 1 - 5

-4 = - 4

and it does work.

The x-coordinate of the vertex of the equation y = 2x2 − 4x + 12 The x-coordinate of the vertex of the equation y = 4x2 + 8x + 3

dolphi86 [110]

So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is $x=\frac{-b}{2a}$ , with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:

y = 2x^2 − 4x + 12: $x=\frac{4}{2*2}=\frac{4}{4}=1$

y = 4x^2 + 8x + 3: $x=\frac{-8}{2*4}=\frac{-8}{8}=-1$

In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.

Describe the location of the point that has the following coordinates. positive abscissa, positive ordinate

Marysya12 [62]

The cartesian plane is composed of four quadrants: quadrant I, II, III and IV. Quadrant I has positive x and y axes. Quadrant II has negative x axis and y axis. Quadrant III has both negative x and y axes while quadrant IV has positive x axis and negative y axis. x value refers to the abscissa while y value refers to ordinate. Answer hence is A
