Shane y Abha obtuvieron una medalla del equipo que requería que su equipo recolectara no menos de 2000 latas para reciclar. Abha
Usimov [2.4K]

Answer: Shane collected more than 911 cans

Step-by-step explanation:

S is the number of cans that shane collected.

A is the number of cans that Abha collected.

We know that:

together collected more than 2000 cans

A + S > 2000

Abha collected 178 more cans that Shane:

A = S + 178

Now, we can replace this equation in the inequality and get:

A + S > 2000

S + 178 + S > 2000

2*S > 2000 - 178 = 1822

S > 1822/2 = 911

This means that shane collected more than 911 cans.

Fourth degree and a single zero of -3
Darya [45]

The degree of a polynomial is the highest power of the polynomial.

The polynomial is \mathbf{P(x) = (x + 3)^4}

The degree is given as:

\mathbf{n = 4}

The zero is given as:

\mathbf{x = -3}

Add 3 to both sides

\mathbf{x  + 3= 0}

From the question, we understand that the polynomial has a single zero.

So, the polynomial is:

\mathbf{P(x) = (x + 3)^n}

Substitute 4 for n

\mathbf{P(x) = (x + 3)^4}

Hence, the polynomial is \mathbf{P(x) = (x + 3)^4}

Which expression is equivalent to log Subscript c Baseline StartFraction x squared minus 1 Over 5 x EndFraction?
Harrizon [31]

The equivalent expression of \log_c(\frac{x^2 - 1}{5x}) is \log_c(x^2 - 1) - \log_c(5x)

<h3>How to determine the equivalent expression?</h3>

The logarithmic expression is given as:

\log_c(\frac{x^2 - 1}{5x})

The law of logarithm states that:

log(a) - log(b) = log(a/b)

This means that the expression can be split as:

\log_c(\frac{x^2 - 1}{5x}) = \log_c(x^2 - 1) - \log_c(5x)

Hence, the equivalent expression of \log_c(\frac{x^2 - 1}{5x}) is \log_c(x^2 - 1) - \log_c(5x)
