Answer:

b^8

Step-by-step explanation:

Answer:

b^8, with m = 8

Step-by-step explanation:

Apply the algebraic rule: (x^a)/(x^b) = x^(a-b)

Note: This rule is true because we can cancel all b factors that occur in both numerator and denominator.

From this rule, we know that (b^10)/(b^2) = b^(10-2)

b^(10-2) can be written b^8

Factor the equation. [tex]3x^2+8x-11[/tex]

Like I said you can't factor this. The GCD is 1 so you can't factor it. The GCD must be 2 or higher.

Answer:

(x - 1)(3x + 11)

Step-by-step explanation:

Given

3x² + 8x - 11

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × - 11 = - 33 and sum = + 8

The factors are - 3 and + 11

Use these factors to split the x- term

3x² - 3x + 11x - 11 ( factor the first/second and third/fourth terms )

= 3x(x - 1) + 11(x - 1) ← factor out (x - 1) from each term

= (x - 1)(3x + 11) ← in factored form

Step-by-step explanation:

In order to figure this question out, you need to count them up. Count up all the runners that are plotted from 3 miles on. Anything before that is under 3 miles, so it doesn't count.

After counting them up, you will find that there are 7 runners marked who ran 3 miles or more. So your answer is 7 runners.
