PLEASE HELP ASAP!! TYSM!! BRAINLIEST!! :)

Answer:

1A) Degree: 3

1B) 4 terms

1C) $7x^3-5x^2-4x+10$

2A) $3m-5n+1$

2B) $-2b^3-3b+3$

Step-by-step explanation:

The given polynomial is $-4x+7x^3-5x^2+10$

Let us rewrite the polynomial in decreasing powers of x.

This gives us the expression;

$7x^3-5x^2-4x+10$ -----> This is called the standard form.

So let us answer the question:

A) The degree is the exponent of the first term when the polynomial is written in standard form.

Degree: 3

B) The terms are separated by + or - signs.

Number of terms: 4

C) Standard form: $7x^3-5x^2-4x+10$

2A) The given expression is $(7m-2n)+(-3n-4m+1)$

We expand using the distributive property to get:

$7m-2n-3n-4m+1$

We regroup the terms to get:

$7m-4m-2n-3n+1$

We simplify to obtain:

$3m-5n+1$

2B) The given expression is $(b^3-2b+4)-(3b^3+b-1)$

$b^3-2b+4-3b^3-b+1$

Regroup the terms to get:

$b^3-3b^3-2b-b+4-1$

We simplify to get:

$-2b^3-3b+3$
