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:
- 11
Step-by-step explanation:
integer = x
Three times what integer, plus eight equals 3x+8
Three times what integer, plus eight equals negative 25. 3x+8= -25
3x+8= -25
3x = -25 - 8
3x = - 33
x = -33/3 = -11

Answer:
square prism
Step-by-step explanation:
Hello! To find this answer, we have to do change/original. 9.73 - 9.60= 0.13. 0.13/9.60 = 0.01354 and other numbers behind it or 1.4% when rounded to the nearest tenth. You have to multiply the decimal by 100 in order to to get the percent form. It rounds up to 1.4 instead of back down to 1.3, because the 5 is in the hundredths place, and when anything 5 or more appears behind the digit you are rounding to, you go up. The percent increase is about 1.4%.
