Factor by grouping x^3-4x^2+7x-28

Komok [63]

Answer:

(x - 4)(x^2 + 7)

Step-by-step explanation:

x^2 is a factor of the first two terms: x^3 - 4x^2 = x^2(x - 4).

7 is a factor of the last two terms: 7(x - 4).

Note how (x - 4) is a factor of the entire four-term expression given above.

Then: x^3-4x^2+7x-28 = (x - 4)(x^2 + 7)

Quadrilateral ABCD is located at A(-2,2), B(-2,4) and D(2,2). The quadrilateral is then transformed using the rule (x+2,y-3) to

Kay [80]

The rule is x+2, y-3 so you apply it to each of these coordinates. Right 2, down 3.
A(-2,2) -> A'(0,-1)
B(-2,4) -> B'(0, 1)
D(2,2) -> D'(4,-1)

How would I graph this inequality?<br> <img src="https://tex.z-dn.net/?f=7x%2B3y%5C%20%20%5Ctextless%20%5C%206-5x" id="TexFormul

Answer:

the graph in the attached figure

Step-by-step explanation:

we have

$7x+3y$

isolate the variable y

Subtract 7x both sides

$3y$

Divide by 3 both sides

$y$

The solution of the inequality is the shaded area below the dashed line

The equation of the shaded line is $y=-4x+2$

The slope of the dashed line is negative $m=-4$

The y-intercept of the dashed line is the point $(0,2)$

The x-intercept of the dashed line is the point $(0.5,0)$

To graph the inequality plot the intercepts and shade the area below the dashed line

using a graphing tool

The length of the hypotenuse of a 30-60 -90 triangle is 14 units. what is the length of the short leg

kifflom [539]

Recall that the short leg is the side opposite the 30 degrees angle. And the ratio of the short leg to the hypotenuse is 1:2.

Let the length of the short leg be x, then,

$\cfrac{x}{14}=\cfrac{1}{2}\\ \\\Rightarrow2x=14\\ \\\Rightarrow x=\cfrac{14}{2}=7$
