It would be 8r^{3} because you have to multiply the exponent by each of the numbers exponents. you may not see it but 2 has a 1 as an exponent and so does r. 1 time 3 is 3 for each therefore each number now has an exponent of 3 and we got rid of the outside exponent. now all you have to do is simplify the 2 to the power of 3 which gives you 8 and that is all

A park has two biking trails. Tailand Trail is 5 3/10 long. Mayland Trail is 2 4/5 miles long. How much longer is Tailand Trail
zvonat [6]

Answer: 2 1/2 miles

Step-by-step explanation:

To subtract fractions with different denominators (in this problem they are 10 and 5), you have to find the least common denominator or LCD (10). Then you have to multiply the numerator and the denominator of 4/5 by 2 to turn the denominator into the LCD (10).

1. So 2 4/5 turns into 2 8/10

2. Then subtract 2 8/10 from 5 3/10 to get the answer 2 1/2

Which equation is equivalent?<br> 4+20=-3x + 8x -11+5<br> 24 =-5x - 6<br> 24 =-5x-16
Anna [14]

Answer:

you should follow this step but this is a different one.just follow the step

Step-by-step explanation:

Simplifying 4(5x + -6) = 16 Reorder the terms: 4(-6 + 5x) = 16 (-6 * 4 + 5x * 4) = 16 (-24 + 20x) = 16 Solving -24 + 20x = 16 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '24' to each side of the equation. -24 + 24 + 20x = 16 + 24 Combine like terms: -24 + 24 = 0 0 + 20x = 16 + 24 20x = 16 + 24 Combine like terms: 16 + 24 = 40 20x = 40 Divide each side by '20'. x = 2 Simplifying x = 2
