What are the two solutions of 2x2 = –x2 – 5x – 1?
Answers
Answer:
The answer is
[tex]x = \frac{ - 5 + \sqrt{13} }{6} \: \: \: \: or \: \: \: x = \frac{ - 5 - \sqrt{13} }{6} [/tex]Step-by-step explanation:
2x² = - x² - 5x - 1
Rearrange the terms and simplify
That's
2x² + x² + 5x + 1 = 0
3x² + 5x + 1 = 0
Using the quadratic formula solve the equation
That's
[tex]x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]From the question
a = 3 , b = 5 , c = 1
So we have
[tex]x = \frac{ - 5\pm \sqrt{ {5}^{2} - 4(3)(1) }}{2(3)} \\ = \frac{ - 5\pm \sqrt{25 - 12} }{6} \\ = \frac{ - 5\pm \sqrt{13} }{6} [/tex]We have the final answer as
[tex]x = \frac{ - 5 + \sqrt{13} }{6} \: \: \: \: or \: \: \: x = \frac{ - 5 - \sqrt{13} }{6} [/tex]Hope this helps you

Step-by-step explanation:
Consider that 1 inch = 2.54 centimeters. Which three statements are true for converting 18 feet to centimeters?
Answers
Answer:
There are 548.64 cm in 18 feet.
Step-by-step explanation:
We know that, 1 inch = 2.54 centimeters.
We need to convert 18 feet to centimeters
Also, 1 foot = 12 inch
Firstly we will convert 18 feet to inch.
18 feet = 12 × 18 inch
= 216 inch
Now to convert 18 feet to centimeters, multiply 216 inch by 2.54 cm as follows :
216 inch = 2.54×216 centimeters
= 548.64 cm
Hence, there are 548.64 cm in 18 feet.

Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)
m = [tex]\frac{6+3}{2-8}[/tex] = [tex]\frac{9}{-6}[/tex] = - [tex]\frac{3}{2}[/tex]
------------------------------------------
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y = 5 - 2x , that is
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2

The 7th term of an AP is 4 and its common difference is -4. What is the first term?
Answers
Answer: 28
Step-by-step explanation:
The 7th term of an AP is 4 and its common difference is -4. The 7th term of an arithmetic progression is written as:
a + 6d = 4
where,
a = first term
d = common difference= -4
a + 6d = 4
a + 6(-4) = 4
a - 24 = 4
a = 4 + 24
a = 28
The first term is 28.
