81 Because 3•3•3•3= 81 then I added the negative sign. but I guess you should do -3•-3=9 then again -3•-3=9. then 9•9 equals 81.
A. f(-3) = -11
If the function is f(x) = 2x - 5, then just replace x with -3 to find f(-3).
f(-3) = 2(-3) - 5
Multiply 2 times -3.
f(-3) = -6 - 5
Subtract -6 minus 5.
f(-3) = 11
There’s the answer.
Answer:
No, because 6² + 8² ≠ 12²
Step-by-step explanation:
In a right angled triangle,
Perpendicular² + Base² = Hypotenuse² (pythagoras theorem)
But in the given triangle; 6² + 8² ≠ 12²
36 + 64 ≠ 144
100 ≠ 144
Perpendicular² + base² ≠ hypotenuse²
Thus the given triangle is not right angled.
