The quadratic formula is x= -b +/- √b²-4ac / 2a

In this problem,

a=6
b=4
c=-3

Now, we can plug this into the formula:

x= -4 +/- √4²-(4)(6)(-3) / (2)(6)
x= -4 +/- √16+72 / 12
x= -4 +/- √88 /12
x= -4 +/- 2√22 /12
x= -2 +/- √22 / 6

So,

x= -2 + √22 / 6
x= -2 - √22 / 6

The area of a patio is 72 square feet. The length of the patio is 1 foot longer than the width. What is the width of the patio?
mote1985 [20]
I know there must be an equation to do this, but there is a simpler way.
Just factor number 72 into two numbers which, when multiplied, equal 72. Two of such numbers are 9 and 8, and you can see that the difference between those two numbers is just 1. So that is the answer to your question - the length of the patio is 9 feet, whereas the width is 8 feet.

The sum of two numbers is 85. twice one number plus four times the other is 218. find the numbers
Nina [5.8K]
X + y = 85
2x + 4y = 218
x = 85 - y 
<span>2(85 - y) + 4y = 218 </span>
<span>170 - 2y + 4y = 218 </span>
<span>170 + 2y = 218 </span>
<span>2y = 48 </span>
<span>y = 24 </span>
<span>x = 61</span>

Answer: The first option.


Step-by-step explanation:

1. The formula for calculate the perimeter is:

P=2l+2w

Where l is the lenght and w is the width.

2. The first perimeter is:

P_1=2(105m)+2(12.5m)=235m

3. If you multiply the dimension by a scale of factor of 2, is the same as write the following expression:

P_2=2(2l+2w)

Where 2l+2w is the first perimeter.

4. Then:

 P_2=2(235m)=470m
