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)

Answer:

Bess has been keeping track of the storm for 14 hours.

Step-by-step explanation:

The tropical storm has been moving at 15 miles per hour.

Bess recorded that the storm moved 135 miles yesterday and 75 miles today. Total distance covered by storm is

$135+75=210$

The relationship between distance speed and time is defined as

$speed=\frac{distance}{time}$

$15=\frac{210}{time}$

$time=\frac{210}{15}$

$time=14$

Therefore, Bess has been keeping track of the storm for 14 hours.

What is 7a+21=56 and what is the solution

asambeis [7]

7a+21=56

Begin by subtracting 21 on both sides:
21-21=0 so the 21 in the left cancels, then 56-21=35

Your new equation will be
7a=35

Finally, divide by 7 on both sides:
7/7=1 and 35/7=5

your answer will be
a=5
