it would be 7 friends because it says at least.
So when your divided fraction by fraction you switch the division sign in the middle to multiplication. For example 3/4 x 1/8 you multiply the 3 and the 8 which is diagonal from each other and the 4 by the 1 which gets you 24/4 .
B. since there are two sides that are 10, that equals 20. the other two sides are unknown, making the width 2w
Explanation:
The first step is to figure out what the equation is. When unconventional math symbols are used, and when there are no grouping symbols identifying operands, that can be the most difficult step. Here, we think the equation is supposed to be ...
![\sqrt[3]{x+1}-2=0](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B1%7D-2%3D0)
It usually works well in radical equations to isolate the radical. Here that would mean adding 2 to both sides of the equation, to undo the subtraction of 2.
![\sqrt[3]{x+1}=2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B1%7D%3D2)
Now, it is convenient to raise both sides of the equation to the 3rd power.

Finally, we can isolate the variable by undoing the addition of 1. We accomplish that by adding -1 to both sides of the equation.

The equation is solved. The solution is x = 7.
-7 is the answer to this question
