Use the Pythagorean theorem:
c - a hypotenuse
a, b - legs
We have: a = 9 and c = 12. Substitute:
<em>subtract 81 from both sides</em>
A Pythagorean triple consists of three positive integers a, b and c, such that
.
is not positive integer.
<h3>The sides of the triangle do not form a pythagorean triple.</h3>
[m(100cm/m)(in/2.54cm)(ft/12)]^2=(25/7.62)^2 ft^2
(9*16)m^2(25ft^2/7.62m^2)(sheets/(4*8)ft^2)≈48.44 sheets
In reality you must buy complete sheets, or integer values, so you would need 49 sheets to cover the floor :P
Answer:
f(-3)= 15
Step-by-step explanation:
f(-3) means x is equal to -3
-3 squared - 2(-3)
-3*-3 -2(-3)
*Negative multiplied by a negative equals a positive
9+6= 15
f(-3)= 15
Hope this helps!
11 1/2 is your answer good luck!
