1. Equivalent Expressions are written quantities that are equal.

To find equivalent expressions, it looks like you can just expand the second expression and then see if it matches the first.

2. So, expand 5(2x+3) using the distributive property.

5(2x+3) = 5×2x + 5×3 = 10x+15

It matches the first expression which means that they are equivalent.

I will also do 2-5 for you to check your work.

3. -2(-6+5) = 12-10 = 2            2 ≠ 12x-10

not equivalent

4. 3(4x+5) = 12x+15              12x+15 ≠ 12x-15  

not equivalent

5. -(-4x-3) = 4x+3                    4x+3 ≠ 4x-3

not equivalent

Answer:

The probability that a student who is involved in a sports team also participated in the prom dance = 0.1344

Step-by-step explanation:

56% of the students are involved in a sport team

56% = 0.56

According to the question, it is stated that 24% of the students at the school that are involved in a sports team also participated in the prom dance.

24% = 0.24

This means that we are going to find 24% of the original 56%, since 24% of them also participated in the prom dance.

The probability that a student who is involved in a sports team also participated in the prom dance = 0.24 * 0.56

The probability that a student who is involved in a sports team also participated in the prom dance = 0.1344

Tell whether the expression 3x^4 -5x +7 is a polynomial. If it is polynomial , find the degrees and determine whether it is a mo
ioda

Given:

The polynomial is:

3x^4-5x+7

To find:

The degrees and determine whether it is a monomial, binomial, or trinomial.

Solution:

We have,

3x^4-5x+7

The highest power of the variable <em>x</em> in the given polynomial is 4. So, the degree of the polynomial is 4.

Monomial: Polynomial with one term.

Binomial: Polynomial with two terms.

Trinomial: Polynomial with three terms.

In the given polynomial, we have three terms 3x^4,-5x,7. So, the given polynomial is trinomial.

Therefore, the degree of the polynomial is 4 and it is a trinomial.
