X^3 = - 216

We know, (-6) x (-6) x (-6) = -216

So x = -6

Answer:

-72

Step-by-step explanation:

First, you do is divide by 3 from both sides of an equation.

\frac{x*3}{3}=\frac{-216}{3}

Then, you divide by the numbers from left/right.

-216/3= -72

I hope this helped!

Evaluate. Write your answer as a fraction in simplest form.<br><br> 2 1/6 −(−8/3)+(−4 7/9)

Snezhnost [94]

Answer:

1/18

Step-by-step explanation:

first, you make the fraction a mixed number so 2 2/3.

second, the two minuses cancel each other out so 2 1/6 + 2 2/3

third, make the 2/3 from 2 2/3 into 4/6 so you can add it to the 2 1/6

fourth, add your 2 1/6 and your 2 4/6 to get 4 5/6.

that’s the first part: 2 1/6 -(-8/3) is equal to 4 5/6

then, since you’re adding a negative number, it’s basically subtracting the 4 7/9 from 4 5/6

first you subtract the whole numbers = 0

then, make the denominators the same: (6*9, common denominator is 54) so since you’re multipling the 9 from 7/9 by 6, also multiply the 7 by 6 to get 42. 42/54. do the same but with a 9 on the 5/6. you get 45/54

so now you can do 42/54 — 45/54 to get 3/54

54/3 is 18 so you can simplify to 1/18

Suppose you have two squares, one of which is larger than the other. Suppose further that the side of the larger square is twice

TEA [102]

Answer:

Area of smaller square: y^2 yards^2,

area of larger square: 4*y^2 yards^2.

Step-by-step explanation:

If the smaller square has a side which length is y yards, its area can be calculated as the square of its side, so:

Area of smaller square = y^2

If the larger square has a side which length is twice as long as the side of the smaller square, its side is equal to 2*y yards, so its area will be:

Area of larger square = (2*y)^2 = 4*y^2

So the area of the smaller square is y^2 yards^2, and the area of the larger square is 4*y^2 yards^2.
