it means to place the little dot (or decimal) in the correct position next the number. Makes sense?
There are no zeroes for an expression, only for equations.
Assuming equation to be
<span>−7x^2 − 91x − 280=0
-7(x^2+13x+40)=0
-7(x+8)(x+5)=0
by the zero product properties,
x+8=0 => x=-8
or
x+5=0 => x=-5</span>
Answer:
52.4
Step-by-step explanation:
40 hundredths as a decimal is 40/100 which is .40.
The "fifty two" is a whole number which is in front of the ".40" which makes 52.4 or 52.40.
