Answer:
64
Step-by-step explanation:
One eighth of the side is one square. Eight squares per side. Eight multiplied by eight is sixty-four.
The hydroxonium ion concentration of the fruit juice whose pH as given in the task content is; 5.6 can be evaluated as; [H3O+] = 2.51 × 10^-6.
<h3>What is the hydroxonium ion concentration of the fruit juice whose pH is 5.6?</h3>
Since the given pH of the fruit juice is 5.6, the hydroxonium ion concentration of the fruit juice can be evaluated by means of the formula as follows;
pH=-log[H3O+].
5.6 = -log[H3O+].
-5.6 = log[H3O+].
[H3O+] = antilogarithm (-5.6)
[H3O+] = 2.51 × 10^-6.

Part A:
We observe that we have the following system of equations:
y = 4x
y = 2x-2
The solution to the system of equations is an ordered pair (x, y), that is, a point in common that both functions have.
Part B:
x y = 4x y = 2x-2
-3 -12 -8
-2 -8 -6
-1 -4 -4
0 0 -2
1 4 0
2 8 2
3 12 4
The solution is the ordered pair:
(x, y) = (-1, -4)
Part C:

Answer:
False
Step-by-step explanation:
Multiply both sides by b ÷ c
I know this isn't usual, but there is nothing illegal about it.
(c/a - a/c) = b÷c * b/a Change b÷c to b/c
c/a - a/c = b/c * b/a Combine the right
c/a - a/c = b^2/(ac) Find the numerator using the LCM ac
(c*c - a*a)/(ac) = b^2/(ac) Multiply both sides by ac
c^2 - a^2 = b^2 This may or may not be true. If there is one false case it is not true.
The statement is false.
c = 10
a = 8
b = 6
10^2 - 8^2 = 6^2 This works.
12^2 - 11^2 = 9^2 will not work.
