This is called ASA
Answer:
7/30
Step-by-step explanation:
The difference means subtracting so 14/15 - 7/10 = 7/30 or decimal form is 0.23
"If and only if" (abbreviated "iff") is a biconditional logical connective between two assertions that is either true or untrue. The correct option is D.
<h3>What is "if and only if" operator?</h3>
In logic and related subjects such as mathematics and philosophy, "if and only if" (abbreviated "iff") is a biconditional logical connective between two assertions that is either true or untrue. It is represented by ⇔ or ↔.
The two of the events are
- p: the whole number has one digit.
- q: the whole number is less than 10.
Now, the representation of "the whole number has one digit if and only if the whole number is less than 10" is done as p ↔ q.
Hence, the correct option is D.

Answer:
x = +2, x = -2
Step-by-step explanation:
The equation to solve in this problem is
The first step we do is to subtract 35 on both sides of the equation, so we get:
Now we simplify the equation by dividing both terms by 10:
Now we observe that the term on the left is the difference between two squares, so it can be rewritten using the property:
Where here,
a = x
b = 2
So we can rewrite the equation as:
And this equation is zero when either one of the two factors is zero, so the two solutions are:
