timama [110]

Hello there!

<u><em>Answer: ⇒⇒⇒⇒⇒ x</em></u>

_____________________________________________________________

Step-by-step explanation:

First you had to divide by 8 from both sides of equation.

\frac{-8(-6x+7)}{8}

Simplify.

6x-7

Then you had to add by 7 from both sides of equation.

6x-7+7

Simplify.

6x

Divide by 6 from both sides of equation.

\frac{6x}{6}

Simplify it should be the correct answer.

x

Let n be an odd integer with exactly 11 positive divisors. Find the number of positive divisors of 8n^3
Tom [10]

Answer: 124

Step-by-step explanation:

As we know, the total number of positive divisors of n is the product of one more than each exponent in the prime factorization of n.

We know this product is equal to 11.

Since 11 is prime, so there can be only one number in this product, so the prime factorization of n must be $n=p^{10}$, where p is a prime number.

We take a cube of the prime factorization of n to give us a prime factorization for n^3

$$n^{3}=\left(p^{10}\right)^{3}=p^{30} .$$

We see that n^{3}\text{ has }$30+1=31$ positive divisors.

Now, 8n^3=2^3\times p^{30}

Totald divisiors = (3+1)(30+1)=4\times31=124

Hence, the number of positive divisors of 8n^3=124

Can you please answer this it’s 7th grade math ixl
xenn [34]

Answer:

W = 8 m

Step-by-step explanation:

The formula for "perimeter" is P = 2L + 2W, where L and W represent the length and the width respectively.

Here, P = 54 m = 2(19 m) + 2W, so:

                54 m = 38 m + 2W, or

                  16 m = 2W, and so W must be W = 8 m
