Answer:
A) No...
Step-by-step explanation:
We can check if this triangle is a right triangle by using the Pythagorean Theorem.
- a² + b² = c²
- where a and b are the legs of the right triangle, and c is the hypotenuse (longest side)
Using 5 for a, 8 for b, and 12 for c, let's see if this satisfies the equation:
Simplify.
We can see that 89 ≠ 144, so this leaves us with answer choices A and B. I think you meant to write < for the last + sign.
Seeing as the sum of the two lengths of the triangle is greater than the third side length, this creates a normal triangle. This cannot be the correct answer choice since this only satisfies the requirements for a triangle, but not a right triangle.
This leaves us with answer choice A. 52 + 32 ≠ 122 and 52 + 32 < 122. (I'm not sure why the squares of the side lengths are not used, but this should be the correct answer.)
Answer:
yes
Step-by-step explanation:
D, because it is the only one that contains multiples. All others contain factors.

Answer:
C
Step-by-step explanation:
A number's absolute value is its distance from zero. -4 is 4 units from zero so its absolute value is 4
Hope this helps!
Pennies (P) = 24
Nickels = 1/2P
Dimes = 1/2P + 5
Quarters = (1/2P + 5) -6
Therefore...
Nickels = 1/2P = 1/2(24)= 12
Dimes = 12 + 5 = 17
Quarters = 17 - 6 = 11
