THEOREM:
• <u>Pythagorean theorem</u>:— In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.
ANSWER:
By pythagorean property,
x² = 4² + 8²
x² = 16 + 64
x² = 80
x = √80 units.
So, <u>Correct choice</u> - [A] √80 units.
C
because you just eliminate it
Answer:
2x^2-4x-6
Step-by-step explanation:
I don't know what kind of math this is, but simply add up all of the like-terms.
There are 2 +x^2 --> 2x^2
There are 4 -x --> -4x
There are 6 - --> -6
Answer:
a = 6
Step-by-step explanation:
first try to divide all numbers by 3 and the add 4 to it until you get 6
Volume of a cone = pir^2h/3
so substitute what you know
1,102.14 = 3.14(r^2)(13/3)
divide by 3.14
351 = r^2(4.3333)
divde by 13/3
81 = r^2
r = 9 inches
