Which statement is true about the polynomial
pantera1 [17]

Question:

Which statement is true about the polynomial

–3x4y3 + 8xy5 – 3 + 18x3y4 – 3xy5 after it has been fully simplified?

It has 3 terms and a degree of 5.

It has 3 terms and a degree of 7.

It has 4 terms and a degree of 5.

It has 4 terms and a degree of 7.

Answer:

Option D: It has 4 terms and a degree of 7.

Explanation:

The given polynomial is 3x^4y^3+8xy^5-3+18x^3y^4-3xy^5

We need to simplify the polynomial to determine the number of terms and the degree of the polynomial.

Hence, the simplified polynomial is given by

$3 x^{4} y^{3}+5x y^{5}-3+18 x^{3} y^{4}$

Term of a polynomial:

The term of a polynomial consists of a number multiplied by a variable or it may be a constant.

Thus, the simplified polynomial has 4 terms.

Degree of a polynomial:

The degree of a polynomial is the sum of exponents of the variables in a term.

Thus, the simplified polynomial has a degree of 7.

Hence, the polynomial has 4 terms and a degree of 7.

Therefore, Option D is the correct answer.

Studying for the act and I'm really bad at math, please help!
Bond [772]
We are given the ratio of 1/2 inch: 18 miles

Multiply both sides of the ratio by 2. I'm doing this so that the "1/2" turns into "1"
So we go from this ratio
1/2 inch: 18 miles
to this ratio 
1 inch: 36 miles
which means that every inch on paper represents 36 miles in real life

----------------------------------------------------------------

The question is now: if two towns are 2.5 inches apart on paper, then how far are they in real life? (note: 2.5 is the decimal form of 2 and a half)

To find out, multiply both sides by 2.5
1 inch: 36 miles
2.5*(1 inch): 2.5*(36 miles)
2.5 inches: 90 miles

--------------------------------------------------------------------------

Answer: The two towns are 90 miles apart in real life
