Mathematics
1 answer:
Igoryamba3 years ago
7 0

Step-by-step explanation:

Given formula

an = n² + 4

Now the first four terms of the sequence are

a1 = 1² + 4 = 5

a2 = 2² + 4 = 4 + 4 = 8

a3 = 3² + 4 = 9 + 4 = 13

a4 = 4² + 4 = 16 + 4 = 20

The terms are

5 , 8 , 13 and 20.

What is the sum of the solutions of x2 + 9x + 20 = 0?
ZanzabumX [31]

Answer:

Sum of the solutions of x^2+9x+20=0 is -9.

Product of the solutions of 6x^2+7x=3 is -0.50

Step-by-step explanation:

1. x^2+9x+20=0

Given:

The expression whose sum of the solution is required is given as:

x^{2} +9x+20=0

For a quadratic equation of the form ax^2+bx+c=0 the sum of the solutions is given as:

Sum = \frac{-b}{a}

Here, a=1,b=9,c=20

Therefore, the sum of the solutions = -\frac{9}{1}=-9

2. 6x^2+7x=3

Rewriting the above equation in a standard quadratic equation, we get:

6x^2+7x-3=0

For a quadratic equation of the form ax^2+bx+c=0 the product of the solutions is given as:

Product = \frac{c}{a}

Here, a=6,b=7,c=-3

Therefore, the product of the solutions = \frac{-3}{6}=-0.50

Math<br><br> 2(8x -4) = 32<br><br> show work
Umnica [9.8K]
<span>2(8x - 4) = 32   distribute through parenthesis
16x - 8 =32  add 8 on both sides to isolate x
16x = 40   divide by 16 on both sides to isolate x
x= 40/16   simplify, Divide 40 by 16 
x = 2.5  this is your final answer, I hope it helps!</span>
