Julio cubes a number and then takes the cube root of the result.He ends up with 20.What number did julio start with

1 answer:

5 0

Cube rooting a number that is the result of cubing a number means you will end up with the original number again.

for example, if you do 3 cubed you get 27, and the cube root of 27 is 3. This means Julio started with the number 20

ANSWER ALL (a-d) FOR 30 POINTS - EASY

Part a.

<span>The perimeter formula is: </span>P = 2w + 2L

Your answer for part A is P = 2w + 2L

Part b.

They tell us in part b, that:
w = 6L + 20

Substitute that into what we got for part a.

P = 2(6L + 20) + 2L
P = 12L + 40 + 2L
P = 14L + 40

Your answer for partb is P = 14L + 40

Part c.

So we take what we got from part b, and solve for L.

P = 14L + 40
14L = P - 40

$L = \boxed{\frac{P-40}{14}}$

That is your answer for part 3 ^

part d.

Plug in w = 32 into what we first got in part b.

w = 6L + 20
32 = 6L + 20
6L = 12

L = 2

Your answer for part d is L = 2
