Helloooo! Marie Here!!

The answer is:

B. (x-6)(x + 2)

Explanation:

If any individual factor on the left side of thee equation is the same as 0 , the entire thing will be the same as x- 6 = 0, x + 6 = 0
Set the first factor the same as 0 and solve it x = 6
Set the next factor equal to 0 and solve it x = -2
The final thing to do is to add all of the answers you got that will make (x - 6) (x + 2) = 0....... x = 6, - 2
And thats how you get B. (x-6)(x + 2)

One angle measures 170°, and another angle measures (6k + 44)°. If the angles are vertical angles, determine the value of k.

Makovka662 [10]

Answer:

21 = k

Step-by-step explanation:

Vertical angles are equal

170 = 6k+44

Subtract 44 from each side

170-44 = 6k+44-44

126 = 6k

Divide each side by 6

126/6 = 6k/6

21 = k

What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?

AnnZ [28]

The value of n in given proportion is 16

Solution:

We have to find the value of "n" in the proportion

Given proportion is:

$\frac{n}{28} = \frac{4}{7}$

We can solve the above proportion by cross-multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

$->\frac{n}{28} = \frac{4}{7}$

$-> 7 * n = 4 * 28$

$-> n = \frac{4 * 28}{7}$

$-> n = 4 * 4 = 16$

Thus the value of n in given proportion is 16

Sandra wrote the sequence shown:

-BARSIC- [3]

Answer:

2n^2 + n + 4.

Step-by-step explanation:

7, 14, 25, 40, 59

The differences are 7, 11, 15, 19 which is arithmetic sequence so the given sequence is quadratic.

Compile a table:

n 1 2 3 4 5

term 7 14 25 40 59

Diff: 7 11 15 19

Diff: 4 4 4 - this indicates that first part is 2n^2.

2n^2 2 8 18 32 50

term-2n^2 5 6 7 8 9

- the nth term for the last sequence is 5+ (n - 1)d =

= 5 + (n - 1)* 1

= n + 4.

So nth term for the original sequence is 2n^2 + n + 4.
