Add parentheses to the equation below so that x = 90. 3 + 2^2 /4 - 10 = x

8090 [49]

Answer:

(3+2)²*4-10=x

Step-by-step explanation:

If it was a typo and is actually times 4, not divided by 4, then here is the answer:

(3+2)²*4-10=x

5²*4-10=x

25*4-10=x

100-10=x

90=x

If it actually was divided by 4, I don’t see any way it can be done.

Find the common ratio of the geometric sequence.

Kay [80]

Answer:

The common ratio is $\frac{1}{x^4}$

Step-by-step explanation:

Geometric sequence:A geometric sequence is a sequence in which the ratio of any term to the preceding term of that term is always constant.

Common ratio: The ratio of any term to the preceding term of that term.

The $n^{th}$ term of a geometric sequence is represented by $a_n=ar^{n-1}$ .

The $1^{st}$ term of the sequence = a.

The sum of first n term is

$S_n=\frac{a(1-r^n)}{1-r}$

The common ratio = r.

Given geometric sequence,

$\frac{1}{x^{10}}$ , $\frac{1}{x^{14}}$ , $\frac{1}{x^{18}}$ , $\frac{1}{x^{22}}$ ........

The common ratio is

$=\frac{\textrm{second term}}{\textrm{first term}}$

$=\frac{\frac{1}{x^{14}}}{\frac{1}{x^{10}}}$

$=\frac{x^{10}}{x^{14}}$

$=\frac{1}{x^4}$
