The product of x and the sum of 6 and 8 times the square of x
Kamila [148]

Let's separate this problem into several parts:

1. The product of x

AND

2. The sum of 6 and 8

TIMES

3. The square of x

So translating this word problem into numbers, we have:

x TIMES (6+8) TIMES x²

so that is:

x * 14 * x²

which is:

14x^(2+1) = 14x³

The scneario here expressed is an aritmetic sequence because it can be explained like this: 

<span><span><span>a1</span>=35
</span><span><span>an</span>=<span>a<span>n−1</span></span>+<span>17

So all the variables can fit in and will be better explained than a geometric sequence in which you need a common ratio and that is not needed in this case</span></span></span>

For what values of K does x2+kx+9=0
Airida [17]

Answer:

k = 6

Step-by-step explanation:

b = k

c = 9

now,

D = b {}^{2}  - 4ac

k {}^{2}  - 4(1)(9) = 0 \\   k {}^{2}  - 36 = 0 \\ k {}^{2}  = 36 \\ k = 6
