Solve 3x2 + 4x + 2 = 0 by using the Quadratic Formula. If necessary, round to the nearest hundredth.
viva [34]

Answer:

Step-by-step explanation:

For this equation: a=3, b=4, c=2

3x2+4x+2=0

Step 1: Use quadratic formula with a=3, b=4, c=2.

x= −b±√b2−4ac / 2a

x= −(4)±√(4)2−4(3)(2)  /  2(3)

x= −4±√−8  /  6

Answer:

No real solutions.

Traduce el enunciado a expresión algebraica La suma de dos números pares consecutivos
garri49 [273]

Answer:

The answer is "Expression: x+(x+2)".

Step-by-step explanation:

Given:

The sum of two consecutive even numbers

Proving:

Let,

The First number is = x

The second consecutive number is = x+2

Calculating value by adding value:

Expression:

\Rightarrow x+(x+2)\\\\

when x= 1, 2, 3 .... it gives:

\Rightarrow  1+(1+2)= 1+3=4\\\\\Rightarrow  2+(2+2)= 2+4=6\\\\\Rightarrow  3+(3+2)= 3+5=8\\

That's why the sum of consecutive numbers is even.

On the first day of vacation, you read one-quarter of a novel. On the second day, you read half of the remaining pages. On the t
olga2289 [7]
A] Let the total number of pages be x, this is equivalent to 1/1
The fraction of novel read on the first day is 1/4 
The remaining fraction of pages will be:
1/1-1/4=3/4
Fraction read on the second day:
1/2×3/4=3/8
The remaining fraction will be:
1-(3/8+1/4)
=1-5/8
=3/8
Thus the fraction read on the third day is 3/8:
therefore:
3/8 represents 108 hence:
x=(1/1)/(3/8)×108
x=288 pages

b] The number of pages read on the second day will be:
(total number of pages)×(fraction of pages read on the second day)
total number of pages=288
fraction read on the second day=3/8
hence number of pages read on this date will be:

=288×3/8
=108
