Let
x-------------> amount added <span>to each side
</span>A-------------> area increased----------> 84 ft²
we know that
A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x²
50+15x+x²=84----------> x²+15x-34=0
<span>solving the second order equation
</span>x1=-17
x2=2
the answer is x=2 ft
So it’s saying that the following set in roster form: (1) N = (x :x is an odd number, 21< × ≤ 35,×€ N)?
It seems to be that the Roster form would do not do anything but the thing is that this listing would give us the output of a set from this problem.
Your answer would be, N = Set of Odd Numbers such that x is greater than 21 and less than or equal to 35 = {23, 25, 27, 29, 31, 33, 35}.
For multiplication, if both integers have like signs, it is always positive. If they have unlike signs it is negative.
For division, if both integers have like signs it is positive. If they have unlike signs it is negative.
It is a single-winner voting system criterion used to compare such systems.
To find the equation, we first need to change the unit as you did correctly:
1 feet = 12 inches
In this case,let's turn the unit of depth to feet:
4÷12
= 1/3 feet
Then we can find the volume in inches:
1/3×162×6
=54×6
=324 ft^3
Therefore the answer is B.324 ft^3 .
Hope it helps!
