Step-by-step explanation:
area of triangle,=1/2*base*height
30=1/2*10/h
h=6cm

Here, we want to simplify the given expression
We shall use the order of simplification for this
The order is PEDMAS
We shall start with the terms in parentheses before we move to the exponents
We have;

Next is the exponent

The next thing to do is to divide

The next thing to do is to multiply

We then proceed to subtract;
Answer:
Ounces
Step-by-step explanation:
Metric tons and tons is too much while kg is too little.
The equation is balanced by the 3's on both sides so that cancels out. we are left with:
x^2-6x=0
we take out an x, leaving us with:
x(x-6)=0
we know that to find the solution [ or "zero's", ] we must set "x"=0, and "x-6"=0.
the solutions are: x=0 and 6.
