That easiliy false. You can prove this by observing that all integers are, in particular, rational numbers. So, for instance, you can think of 4 as 
, so 
And obviously, you have 
It is true that the square of every rational number between 0 and 1 is smaller than the number itself.
But since not all rational numbers are between 0 and 1, the general claim is false.
Answer:
see explanation
Step-by-step explanation:
The 2 marked angles are vertical and congruent, thus
24x = 23x + 5 ( subtract 23x from both sides )
x = 5
Thus angles = 24 × 5 = 120°
Answer:
c) 2/15
Step-by-step explanation:
LA= 2/3 = 10/15
S=1/5 = 3/15
15/15 - 13/15 = 2/15
Math books= 2/15
<span>3x^2 - 4 = 7x is the standard form. To get standard form into quadratic you must have one side of the equation equal zero. The easiest way to so is subtracting 7x on both sides of the equation.
</span><span>3x^2 - 4 = 7x
-7x -7x
3x^2 -7x - 4 = 0
So, </span>3x^2 -7x - 4 = 0 is the quadratic form.
Answer:
D
Step-by-step explanation:
We have the expression:
First, let's distribute the negative on the right. This gives us:
Now, let's combine like terms:
Add:
Subtract:
Simplify:
So, our answer is D.
And we're done!
