Answer:

Cubic trinomial

Step-by-step explanation:

The degree of a term is the sum of the exponents of its variables

Quadratic: a polynomial of degree two
Cubic: a polynomial of degree three

Therefore, -5x³ - 4x + 1 is a cubic (since the sum of the exponents is 3)

monomial: a polynomial with exactly one term
binomial: a polynomial with exactly two terms
trinomial: a polynomial with exactly three terms

Therefore, -5x³ - 4x + 1 is a trinomial (as it has exactly 3 terms)

lcm for cuberoot

that is 2*2*2*5*5*5*3*3*3

make pairs of three common numbers and write them as one.

2*5*3=30

ans =30

check 30*30*30=27000

cube

multiply 27000 three times with itself

27000*27000*27000

Factor the polynomial.<br><br> X2-13x+30

Svetllana [295]

Answer:

<h2> $\ \boxed{(x - 3)(x - 10)}$ </h2>

Step-by-step explanation:

${x}^{2} - 13x + 30$

Write -13x as a difference

${x}^{2} - 3x - 10x + 30$

Factor out x from the expression

$x(x - 3) - 10x + 30$

Factor out -10 from the expression

$x(x - 3) - 10(x - 3)$

Factor out x-3 from the expression

$(x - 3)(x - 10)$

Hope I helped!

Best regards!!

How do we calculate 25% of 300

Natali5045456 [20]

25% is equal to $\frac{1}{4}$ . To get 25% of 300, we multiply 300 by either 0.25 or $\frac{1}{4}$ . This gives us $(300)( \frac{1}{4}) = \frac{300}{4} = \frac{150}{2} = 75$
