<h2><u>Answer</u><u>:</u><u>-</u><u>1</u><u>9</u><u>3</u></h2>

Step-by-step explanation:

<h3>Given equation:<u>-</u><u> </u><u>6x²</u><u> + x - 8 = 0</u></h3>
  • we know that the discriminant of a quadratic is the expression inside the radical of the quadratic formula.
<h3 /><h3><u>lets </u><u>see:</u><u>-</u></h3>

  • 6x² + x - 8 = 0
  • b²-4(ac)
  • here a= 6,b=1,c=-8
  • (1)²-4(6×(-8))
  • 1-4(-48)
  • 1+192
  • 193

22. Many rectangles have a perimeter of 81 feet. Find the dimensions for the one with the maximum enclosed area.
melisa1 [442]
Let
x----------> the length of the rectangle
y---------> the width of the rectangle

we know that
perimeter of rectangle=2*[x+y]
area of rectangle=x*y
P=81 ft
so
81=2*[x+y]-----------> 40.5=[x+y]

case <span>A) 20.25 feet × 20.25 feet
P=2*[20.25+20.25]-----> 81 ft----------> the perimeter is ok
A=20.25*20.25-----> 410.06 ft</span>²

case <span>B) 11 feet × 29.5 feet
</span>P=2*[11+29.5]-----> 81 ft----------> the perimeter is ok
A=11*29.5-----> 324.5 ft²

case <span>C) 9 feet × 9 feet
</span>P=2*[9+9]-----> 36 ft----------> the perimeter is not 81
A=9*9-----> 81 ft²

case <span>D) 17.5 feet × 23 feet
</span>P=2*[17.5+23]-----> 81 ft----------> the perimeter is ok
A=17.5*23-----> 402.5 ft²

the answer is
case A) 20.25 feet × 20.25 feet

Pat and his friend rent an apartment together. Their total cost to move in included first months rent, last months rent and a se
zimovet [89]

Answer:

a.$375

Step-by-step explanation:

In order to calculate this you just have to keep in mind the amount of months that they paid in advance in the payment, so they had 2 months of rent fully paid in advance, we will represent that with "x", so we have 2x as the number of months, and it doesn´t say that they are paying unequal amounts of money so we will assume that they are paying half each of everything, so the equation will look like this:

Total payment: 2 months of rent+security deposit

If total payment= $1050 each, that means that for the two of them it´d be $2100, now we know that they paid 2 months plus a security deposit of $600, we just have to clear the payment to discover how much does the rent a month cost:

Total payment: 2 months of rent+security deposit\\Tp=2x+600\\Tp-600=2x\\x=\frac{Tp-600}{2} \\x=\frac{2100-600}{2} \\x=750

So one month of rent costs $750, if you divide that by 2, you get that Pat´s share of rent a month is $375.
