How is 6 a solution for 2x^2+4x=3+3x^2

weqwewe [10]

2x^2+4x-3-3X^2=0
simplify 2x^2+4x-3-3x^2 to -x^2+4x-3
-x^2+4x-3=0
Multiply both sides by -1
x^2-4x+3=0
Factor x^2-4x+3
1. Ask: Which two number add up to -4 and multiply to 3.
2. Answer:3 and -1.
3. Rewrite the expression as (x-3)(x-1):
(x-3)(x-1)=0
5Solve for x
1.Ask: when will (x-3)(x-1) equal zero.
2.Answer: when x-3=0 or x-1=0.
x=3,1

The equation of the tangent to the curve x^2 = 4y at the point on the curve where x=-2 is?

aleksandrvk [35]

$x^2 = 4y \Rightarrow y= \frac{x^2}{4}$
$\frac{dy}{dx} = \frac{2x}{4} = \frac{x}{2}$

(x = -2) $\frac{dy}{dx} = \frac{x}{2} = \frac{-2}{2} = -1$
(x = -2) $y= \frac{x^2}{4}= \frac{(-2)^2}{4} = 1$

$y-y_1=m(x-x_1)$
$y-1 = -1(x--2)
$
$y-1 = -1(x+2)$
$y-1 = -x-2$
$y=-x-1 = -(x+1)$

A rectangular room is 12 feet wider than its a long how many 1 ft.² tiles does it take to tile along the inside of the room let

Ludmilka [50]

Answer:

Number of of tiles will be $x^2+12x$ .

Step-by-step explanation:

Given:

let 'x' represent the length of the room.

Width is 12 feet wider than its length.

Width = $x+12$

Area of tiles = $1 ft^2$

We need to find number of tile along the inside of the room.

First we will find Area of room.

Area of room will be equal to length times width.

framing in equation form we get;

Area of room = $x(x+12)= x^2+12x$ sq. ft.

Now Number of Tiles will be equal to Area of room divided by Area of tile.

framing in equation form we get;

Number of Tiles = $\frac{x^2+12x}{1} = x^2+12x$

Hence Number of of tiles will be $x^2+12x$ .
