Answer:

$x^3+8x^2+2x+1$

Step-by-step explanation:

Combine like terms (terms with the same exponent).

$x^3+(3x^2+5x^2)+(x+x)+1=x^3+8x^2+2x+1$

"Standard form" means to list terms so the exponents go from high to low (descending order).

Sphinxa [80]

Answer:

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

There is a trigonometric acronym for this which is:

Soh Cah Toa

Soh means that sine is opposite over hypotenuse.

Cah means that cosine is adjacent over hypotenuse.

Toa means that tangent is opposite over adjacent.

Let me actually write these out as fractions:

sine is $\frac{\text{opposite}}{\text{hypotenuse}}$

cosine is $\frac{\text{adjacent}}{\text{hypotenuse}}$

tangent is $\frac{\text{opposite}}{\text{adjacent}}$

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent
