What are the solutions of 3x2 + 14x + 16 = 0?

1 answer:

6 0

IF the original question is 3x² + 14x + 16 = 0
THEN the answer is as follows:

3x² + 14x = -16
x(3x + 14) = -16

x = -16
3x + 14 = -16

3x = -30
x = -3

Not sure where you are getting the fractions from, I assume it is because the equation was not represented correctly in your question.

Answer:

ST=8.8

SR=15.5

Step-by-step explanation:

ST is the difference between S and T.

that would be 16.3-7.5=8.8

similarly RT is the difference between S and R

That would be 7.5-(-8)=15.5.

2 less then 3 times a number is 9

Masteriza [31]

$\huge\boxed{\text{As an expression:}\ 3x-2=9}$

$\huge\boxed{\text{Solved for x:}\ x=\frac{11}{3}}$

Let's start with " $3$ times a number". We will use $x$ to represent the number. $3x$

" $2$ less than" is next. $-2$

Finally, "is $9$ ". $=9$

Put it all together to get an expression. $\boxed{3x-2=9}$

Now, let's solve for the unknown number.

Add $2$ on both sides of the equation. $3x=11$

Divide both sides of the equation by $3$ to isolate $x$ . $x=\boxed{\frac{11}{3}}$

Use the multiplication principle to tell the total number of three-card hands (permutations) that can be made with two aces

alina1380 [7]

We are asked for the total or three card hands that can be made with two aces. The three-card hand should have two aces. We will use permutation in solving this problem and the solution is shown below:
nPr = n! /(n-r)!
n=3
r=2
3P2 = 3!/(3-2)!
3P2 = 6

The answer is 6.
