The variables A, B, and C represent polynomials where A = x2, B = 3x + 2, and C = x – 3. What is AB – C2 in simplest form?

Answers

Answer 1

Answer:

Answer:

$AB-C^2$ in simplest form:

$3x^3+x^2+6x-9$

Step-by-step explanation:

The distributive property says that:

$a \cdot (b+c) =a\cdot b+ a\cdot c$

Given that:

The variables A, B, and C represent polynomials

Where,

$A = x^2$

$B = 3x+2$

$C = x-3$

We have to find the $AB-C^2$

then;

$AB-C^2$ = $(x^2)(3x+2)-(x-3)^2$

Apply the distributive property :

$(3x^3+2x^2)-(x-3)^2$

⇒ $3x^3+2x^2-(x^2+9-6x)$

Remove the bracket, we have;

$3x^3+2x^2-x^2-9+6x$

Combine like terms;

$3x^3+x^2+6x-9$

Therefore, $AB-C^2$ in simplest form: $3x^3+x^2+6x-9$

Answer 2

Answer: AB - C2 = (x2)(3x + 2) - (x-3)2
AB - C2 = 3x3 + 2x2 - (x2 -6x +9)
AB - C2 = = 3x3 + 2x2 - x2 + 6x - 9
AB - C2 = = 3x3 + x2 + 6x - 9

Sin θ = − 8/17 and θ is in Quadrant III, find tan(θ/2)

Answers

Answer:

tan(θ/2) = -0.25

Step-by-step explanation:

sin(x) = -8/17

x = sin^-1(-8/17)

x = -28.07

tan(θ/2) = tan(-28.07/2)

= -0.25

~ALGEBRA! PLEASE HELP!~Austin is climbing on a ladder that is attached against the side of a jungle gym wall. He is 5 feet off the ground and 3 feet horizontally from the base of the ladder, which is 15 feet from the wall. How high up the wall is the top of the ladder?
~Please show work :)

Answers

so I get it now!

so he is currently 5 feet vertically form the wall
he is currently 3 feet horizonatlly from the wall
the ladder's base is 15 total feet from the wall

height:base=5:3

to find the total height
x:15
multiply 5:3 by 5
25:15

so the top of the ladders's vertical height is 25 feet

so the answer is the ladder is 25 feet from the ground

Micah has 294 songs stored in his phone which is 70% of the songs that Jorge has stored on his phone. How many songs are stored on Jorge's phone?

Answers

Since we know that 70% of then number of Jorge's songs is 294, we can represent this with the ratio 70/100 (70%) = 294/x, with x being the total number of songs Jorge has.
To solve this, cross multiply.
70 * x = 100 * 294 ----------> 70x=29400
Divide both sides by 70
x=420

Answer:

jorge has 420 song
