Answer:
f(3) = 42
Step-by-step explanation:
f(x) = 3x² + 5x
Then
f(3) = 3(3)² + 5(3)
= 3×9 + 5×3
= 27 + 15
= 42
Using Pythagorean theorem, the answer should be 8.7ft

Answer:
x = 10
Step-by-step explanation:
You can compare parts of each expression to see that x in the left-side expression is replaced by 10 in the right-side expression.
x = 10
__
If you'd rather, you can work your way down to the same conclusion by undoing the operations that have been done to x.
(6x -1)° = (6(10) -1)° . . . . . . given
6x -1 = 6(10) -1 . . . . . . . . . divide both sides by °
6x = 6(10) . . . . . . . . . . . . add 1 to both sides
x = 10 . . . . . . . . . . . . . . . . divide both sides by 6
