Answer:
Step 3
Step-by-step explanation:
x^3=3
you need to root cube both side not divide both side by 3
You cannot just divide the cube (^3) by 3 to make it 1/
Answer:tienes que estar bromeando
Step-by-step explanation:
Given:

If we need to find what
is, we can solve for a and plug it in. Let's use the quadratic formula to solve for a. The quadratic formula is:
and 
Let's identify our a, b, and c:
a: 1
b: 3
c: 9
Plug in the values into the quadratic formula:

Simplify everything under the radical:

Simplify the radical:

-----------------------------------------------------------------------------
Let's solve for the second part of the quadratic formula. Everything will be the same, so we can just replace the + with a -.
and 
These two are your answers. Now, since we know what a is, let's cube this value:

Simplify:

You will get the same answer if you cube both of the quadratic answers. So, your final answer:

Answer:
2 triangle surfaces: 2.5 X 2 X 1.7 = 8.5 square meters
9 X 2 = 18 square meters
18 X 3 = 54 square meters
54 + 8.5 = 62.5 square meters
What we are saying here is 136 students represent the rest of the students which is 100% minus 15% or 136 represents 85%. All we need to do ( there are several ways but I prefer this one) divide 136 by 85 then multiply by 100 to find answer which is 160
