What is the simplest form of 3x^3 + x^2 + 2 ( x^3 - 4x^2 )

viva [34]

Answer:

−8x^4 + 5x^3 + x^2

Step-by-step explanation:

3x^3 + x^2 + 2 (x^3 − 4x^4)

Apply the distributive property.

3x^3 + x^2 + 2x^3 + 2 (−4x^4)

Multiply −4 by 2.

3x^3 + x^2 + 2x^3 − 8x^4

Simplify by adding terms.

Add 3x^3 and 2x^3.

5x^3 + x^2 − 8x^4

Simplify the expression.

Move x2.

5x^3 − 8x^4 + x^2

Reorder 5x^3 and −8x^4.

−8x^4 + 5x^3 + x^2

What is an equation of the line, in point-slope form, that passes through the given point and has the given slope? point: (8,-8)

creativ13 [48]

Point slope is y-y1= m(x-x1) where m is slope

Plug the values in:
y-(-8)=3(x-8)

Simplify:
y+8=3(x-8)

If (a^2 + b^2) (x^2 +y^2) = (ax + by )^2 then which relation is true?

NikAS [45]

Answer:

Step-by-step explanation:

Hello,

Let's develop both expressions and try to re factorise.

$\forall (a,b,x,y) \in \mathbb{R}^4 \\ \\ (a^2+b^2)(x^2+y^2)=(ax+by)^2\\ \\(ax)^2+(ay)^2+(bx)^2+(by)^2=(ax)^2+(by)^2+2(ax)(by)\\ \\ (ay)^2+(bx)^2-2(ay)(bx)=0\\ \\ (ay-bx)^2=0\\ \\ ay-bx=0\\ \\ \boxed{\sf \bf ay=bx}$

Thanks

PLZ ANSWER PLZ PLZ PLZ HELP 1 QUESTION!!!

JulsSmile [24]

We first must find the value of angle z.

Angle z = 90° - 42°

Angle z = 48°

We now use the sine function to find y.

sin(48°) = 35/y

y = 35/sin(48°)

y = 47.0971455362

We now round off to two decimal places.

y = 47.10

I hope this helps....
