Answer:
The solutions of the original equation are x=-5 and x=-2
Step-by-step explanation:
we have
Let
Rewrite the equation
Complete the square
rewrite as perfect squares
square root both sides
the solutions are
u=-2,u=1
<em>Alternative Method</em>
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
the solutions are
u=-2,u=1
<em>Find the solutions of the original equation</em>
For u=-2
---->
For u=1
---->
therefore
The solutions of the original equation are
x=-5 and x=-2
we know that
The volume of a cylinder is given by the formula
where
r is the radius of the cylinder
h is the height of the cylinder
in this problem
Substitute the values in the formula above
therefore
<u>the answer is</u>
The volume of the can is equal to
Answer:
He must sell 800 bushels.
Step-by-step explanation:
Divide 2400 by 3, giving you 800.
Answer:
the answer will be 5.
Step-by-step explanation:
Do you mean exponential form as in scientific notation or as in prime factorization.
Now matter I will do both.
As in scientific notation.
200*75
=150*100
=1.5*10000
=1.5*10^4
As in prime factorization.
200*75
=2^3*5^2*3*5^2
=2^3 * 3 * 5^4
Do the one your teacher ask for :) Hope it helps!
