Answer:
-7
Step-by-step explanation:
You use the quadratic formula of [tex]ax^{2} +bx+c = 0[/tex] to get:
a = 1
b = 7
c = -13
then you plug that into x= (-b ± √b²-4ac)/(2a) :
x= ( -7 ± √7²- 4(1)(-13) )/(2(1))
[tex]x=-\frac{7}{2} + \frac{\sqrt{101}}{2} \\\\x=-\frac{7}{2} - \frac{\sqrt{101}}{2}[/tex]
The sum of these two x values turns out to be:
[tex]x=-\frac{7}{2} + \frac{\sqrt{101}}{2}+( -\frac{7}{2} - \frac{\sqrt{101}}{2} )= -\frac{14}{2} = 7[/tex]

Katya cut part of the jump rope off to make it shorter. The new length is 8 and StartFraction 1 over 6 EndFraction feet. The difference between the original length and the new length is StartFraction 5 over 6 EndFraction foot. The equation x minus 8 and StartFraction 1 over 6 EndFraction = StartFraction 5 over 6 EndFraction can be used to represent this problem, where x is the original length of the rope. What was the original length of the rope?

⇔ x = 3/4 .18 = 27/2 = 13.5
Step-by-step explanation:
Answer:x = 27/2
Step-by-step explanation:
Step 1: Cross-multiply
3/4=x/18
(3)*(18)=x*(4)
54=4x
Step 2: Flip the equation.4x=54
Step 3: Divide both sides by 4x/4=54/4x
= 27/2

The rectangle and the trapezoid have the same area. What is the length l of the rectangle?
l=
ft
The length 'l' of the rectangle will be;
⇒ l = 18 feet
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The rectangle and the trapezoid have the same area.
Now,
Since, The rectangle and the trapezoid have the same area.
Hence, We get;
Area of rectangle = l × 9
And, Area of trapezoid = 1/2 (24 + 12 ) × 9
= 1/2 × 36 × 9
= 18 × 9
= 162
So, We get;
⇒ l × 9 = 162
⇒ l = 162/9
⇒ l = 18 feet
Thus, The length 'l' of the rectangle will be;
⇒ l = 18 feet
