MArishka [77]2 years ago
8 0

Answer:

(8x2−4x−8)(2x+3x+2)

=(8x2+−4x+−8)(2x+3x+2)

=(8x2)(2x)+(8x2)(3x)+(8x2)(2)+(−4x)(2x)+(−4x)(3x)+(−4x)(2)+(−8)(2x)+(−8)(3x)+(−8)(2)

=16x3+24x3+16x2−8x2−12x2−8x−16x−24x−16

=40x3−4x2−48x−16

Equation with a slope of -2 and point of (4,7)
s344n2d4d5 [400]

Answer:

y=-2x+15

Step-by-step explanation:

So first we can write it in point slope form.

That is y-y1=m(x-x1)

y1 is the y coordinate

m is the lope

x1 is the x coordinate

This means that the equation is:

y-7=-2(x-4)

We can then convert it to slope intercept form which is

y=mx+b

so

y-7=-2x+8

y=-2x+15

What are the coordinates of the fourth point that could be connected with (–8, 0), (1, 0), and (1, –5) to form a rectangle?
Ksju [112]
(-8,-5). If you think about it, for a rectangle, the x-coordinates must be the same in two pairs and the y-coordinates must be the same in two pairs. Since there are already 2 0's, 2 1's, you need a -8 and -5 to complete it. Hence, the last coordinate is (-8,-5)

Find the missing side of the triangle. leave your answer in simplest radical form
KIM [24]

missing side is x} = 10.15 mi .

<u>Step-by-step explanation:</u>

Here we have the following info from the figure: A right angled triangle with following dimensions

Perpendicular = x

base = \sqrt{122}

Hypotenuse = 15

By Pythagoras Theorem :

Hypotenuse^2 = Perpendicular^2 + base^2

⇒ Hypotenuse^2 = Perpendicular^2 + base^2

⇒ 15^2 = x^2 + (\sqrt{122})^2

⇒ 225 = x^2 + 122

⇒ x^2 = 225-122

⇒ x^2 = 103

⇒ (x^2)^\frac{1}{2} = (103)^\frac{1}{2}

⇒ x} = (103)^\frac{1}{2}

⇒ x} = 10.15

Therefore, missing side is x} = 10.15 mi .
