Answer:

100r^4 + 400r^3 + 600r^2 + 400r + 100

Step-by-step explanation:

Expanding ( r + 1 )^4 gives :-

r^4 + 4r^3 + 6r^2 + 4r + 1

So multiplying 100 with r^4 + 4r^3 + 6r^2 + 4r + 1 gives :-

100r^4 + 400r^3 + 600r^2 + 400r + 100

Rewrite in simplest radical form: x^4/5 / x^1/3 into a√x^b

mrs_skeptik [129]

Answer:

$\sqrt[15]{x^7}$

Step-by-step explanation:

If we have the expression

$\frac{x^{\frac{4}{5}}}{x^{\frac{1}{3}}}$ , we have to think about exponent rules.

If we have $a^b \div a^c$ , then the value will be equal to $a^{b-c}$ .

So $\frac{x^{\frac{4}{5}}}{x^{\frac{1}{3}}}$ simplified will be $x^{\frac{4}{5} - \frac{1}{3}}$

Converting $\frac{4}{5}$ and $\frac{1}{3}$ into fifteenths (lcm) gets us $\frac{12}{15} - \frac{5}{15} = \frac{7}{15}$ .

We can convert $x^{\frac{7}{15}}$ into a radical by taking the denominator root of x to the numerator.

$\sqrt[15]{x^7}$ .

Hope this helped!

What’s the answer for -3(r-4)_>0

Zigmanuir [339]

Answer:

r<4

Step-by-step explanation:

-3(r-4)>0 step 1: distribute the -3

-3r+12>0 explain: -3 times r =-3r, -3 times -4 = 12

next, isolate the -3r by putting 12 on the other side

-3r+12>0 subtract 12 from both sides

-3r>-12 now, divide both sides by -3 (you have to flip the > because you are dividing by a negative) -12 divided by -3 is 4

so you should end up with r<4

Andy has a collection of movie dvds. in andys collection 3/5 of the dvds are action 1/4 of the dvds are comedy. andy said that 4

Lerok [7]

If 3/5 are action and 1/4 are comedy then:

(3/5)+(1/4) are action or comedy

To add/subtract fractions you need a common denominator...

(3/5)*(4/4)+(1/4)(5/5)

(12/20)+(5/20)

17/20

So 17/20 (85%) of his collection are action or comedy not 4/9...
