Answer:
Given:
The pH of solution A = 2.4
The pH of solution B = 9.4.
Solution:
The hydrogen ion concentration is the amount of hydrogen ions present in the given solution usually expressed in terms of moles pere litre .
(A) hydrogen-ion concentrations of the solution.

Now,
The hydrogen ion concentration of the solution A


Similarly
hydrogen ion concentration of the solution B


(b) The hydrogen ion concentration of solution A
is and the solution B is 
so we can conclude that the hydrogen ion concentration of solution A is
times greater than solution B
(c) The solutions A and Solution B differ by 7 order of magnitude
Yes, If the two numbers have no factors in common then they are relatively prime.
(4) 64 tiles, (5)
, (6) 
Step-by-step explanation:
Given data: Side length of square tile = 1 ft
(4) Side length of square pool = 8 ft


= 64
Hence 64 tiles needed for the border.
(5) Suppose number of square tiles be N and side of square tub is s ft.
So, N = 

So, the expression is
.
(6) The equivalent expression is
.
The polynomial
is in standard form if the exponents are arranged in decreasing order.
<h3>
Polynomial in Standard Form</h3>
Polynomial is an algebraic expression with one or more terms. For example :
. In this example and in your exercise the exponents of the terms are not arranged in order.
Um polynomial is in <u>Standard Form</u> when the exponents of the terms are in decreasing order. See more details below.
is not in standard form because the exponents are not written in decreasing order.
is in standard form because the exponents are written in decreasing order.
Therefore, the given polynomial will be in standard form if yours exponents are arranged in decreasing order.
