All together he made 23.40
One third of $17.55 is $5.85
When you add $17.55 and $5.85 together you get $23.40
23+8X is the answer to this problem
Answer:
(x-10)(x+10)
Step-by-step explanation:
x^2 – 100
This is the difference of squares
x^2 - 10^2
We know that (a^2 - b^2) = (a-b) (a+b)
(x-10)(x+10)
Answer:
Step-by-step explanation:
If that is a square, then all sides are the same. Therefore, it's a 
by shape. We'll use Pythagorean Theorem to find the diagonal.
Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!
