I need to solve this problem

Mathematics
1 answer:
Sauron [17]3 years ago
5 0

Step-by-step explanation:

so, all 3 pieces together are 20 inches.

therefore,

x + 4x + 5x = 20

10x = 20

x = 2

so, the first piece is 2 inches long.

the second piece is 4×2 = 8 inches long.

the third piece is 5×2 = 10 inches long.

The recursive definition for the geometric sequence is given as follows:

a_n = 3a_{n-1}, a_1 = 1.7

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

a_n = a_1q^{n-1}

In which a_1 is the first term.

The recursive definition of a geometric sequence is given by:

a_n = qa_{n-1}

In this problem, we have that the first term and the common ratio are given, respectively, by:

a_1 = 1.7, q = \frac{15.3}{5.1} = \frac{5.1}{1.7} = 3.

Hence the recursive definition is given by:

a_n = 3a_{n-1}, a_1 = 1.7

(7x²+2x+5)+(3x²-8x-10)
Mariulka [41]
First you would simplify the equation <span>(7x²+2x+5)+(3x²-8x-10) lets start with the first part 
</span><span>(7x²+2x+5) 
</span>7x² + 2x which = 49x + 2x which also = 51x Then you add the last part (+5) 
51x + 5
Now you simplify the last part.
<span>(3x²-8x-10)
</span>3x²-8x which=9x - 8x which also = 1x or simply x Then add the last part (-10) Which you'll get x-10 
51x + 5) + (x - 10) = 52x -5
so your answer is 52x - 5
