<span> A(n) = 5.3^(n-1)
first term A(1) = 5.3^(1-1)= 5.3^0 = 5.1 = 5
fourth term A(4) = 5.3^(4-1) = 5.3^3 = 5x27 = 135
8th term A(8) = 5.3^(8-1) = 5.3^7 = 5.3^3.3^3.3 = 5x27x27x3= 15x729 = 10935</span>


hope this helps! ;)

Need some help with multiplying algebraic fractions
Nezavi [6.7K]

Answer:

a=10, b=5, c=2, d=12

Step-by-step explanation:

Multiply each variable together

5*2=10

8*3=24

10x^{3}y^{2}/24x

the coefficients (numbers) can each be divided by 2

5x^{3} y^{2}/12x

subtract the "x" exponents together

5x^{2} y^{2}/12

What’s the result ????????????????
Mrrafil [7]

Answer:

Option 1

Step-by-step explanation:

You must multiply (2x + 3) by (x + 4). I use the FOIL method.

(2x + 3)(x + 4)

Multiply

2x² + 8x +3x + 12

Simplify

2x² + 11x + 12

To check the answer, you could factor this trinomial back into a pair of binomials.

Compare the process of solving |x – 1| + 1 &lt; 15 to that of solving |x – 1| + 1 &gt; 15. Check all of the following you includ
zepelin [54]

The required Comparison of the inequalities are

  • The |x – 1| + 1 > 15 represents the value of x lies between 13<x<15.

The range of values encompassing the region's junction is (-13, 15).

  • If x is more than or equal to 15, then x-11+1>15 indicates the value of x is greater than or equal to 13. None of the regions in the intersection are empty.

<h3>What is inequality?</h3>

When comparing two numbers, an inequality indicates whether one is less than, larger than, or not equal to the other.

We take into account the various variables of the inequality

|x – 1| + 1 > 15

Therefore

|-x-1|+1-1<15-1

|-x-1|-1 <14

13<x<15

The required region lies between the inequality -13 <x< 15.

Simplify the inequality Ix-11+1 > 15 we get,

|x-1|+1 > 15

|x+1| +1-1 >15-1

|x-1| > 14

x> 15  

x<-13

  • If x has a value between -13 and x + 15, then the expression "|x-1|+1+115" is true. The range "(-13, 15)" contains the intersection of the region.
  • If "|x-1|+1>15" then either "x >15" or "x-13" applies to the value of x. This region's intersection is unoccupied.
