Find x. Round to the nearest tenth.

In-s [12.5K]

Answer:

x = 4.9

Step-by-step explanation:

We can use the intersecting chords formula:

(segment piece) x (segment piece) = (segment piece) x (segment piece)

7*7 = 10x

49 = 10x

Divide each side by 10

49/10=10x/10

4.9 = x

Subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x.

kicyunya [14]

Simplified value of subtraction of 7x+27x+2 from -5x^2-2x−5x 2 −2x. is $-10x^{2} -38x-2$ .

Given Expressions 7x+27x+2 and -5x^2-2x−5x 2 −2x.

Expressions refers to the combination of numbers, variables and symbols. It represents the relationship between variables. They are solved for finding out the value of variables. It is mainly not in equal to form. Subtraction is possible when subtracting the coefficients of same variable.

We have to subtract 7x+27x+2 from -5x^2-2x−5x 2 −2x. and to do this we need to first solve the expressions itself.

7x+27x+2=34x+2------------------1

$-5x^{2} -2x-5x^{2} -2x$ = $-10x^{2} -7x-2x$ --------------------2

Now subtract 1 from 2

= $-10x^{2} -7x-2x$ -34x+2

= $-10x^{2} -38x-2$ .

Hence the simplified value of subtraction is $-10x^{2} -38x-2$ .

Identify the 27th term of an arithmetic sequence where a1 = 38 and a17 = -74. . A. -20.5 . B. -151 . C. -22.75 . D. -144 . .

Dennis_Churaev [7]

In order to solve for a nth term in an arithmetic sequence, we use the formula written as:

an = a1 + (n-1)d

where an is the nth term, a1 is the first value in the sequence, n is the term position and d is the common difference.

First, we need to calculate for d from the given values above.
<span>a1 = 38 and a17 = -74
</span>

an = a1 + (n-1)d
-74 = 38 + (17-1)d
d = -7

The 27th term is calculated as follows:

a27 = a1 + (n-1)d
a27= 38 + (27-1)(-7)
a27 = -144 -----------> OPTION D
