f(x) = sqrt(x)
f(17) = sqrt(17)
it is close to sqrt(16)=4
so to the nearest integer
f(17) = 4
Answer:

Step-by-step explanation:
In a right triangle the tangent of an angle is the ratio of the opposite length over the adjacent*. In formulas,
Solving for x, using a calculator for the tangent, 
*I promise I didn't just spellcheck that.
A rectangle, is a quadrilateral with all angles at 90°.
a square is a quadrilateral with all equal sides, and right-angles all around.
now, the rectangle as well as the square, have all right-angles, the only difference is that the square has all equal-length sides, whilst a rectangle can have pairs of sides that vary in length.
(3x + 1) (2x + 7)

Answer:
x=37/20
Step-by-step explanation:
4(2x-7)+3(3x-1)=3(2-x)
8x-28+9x-3=6-3x
17x+3x=6+31
20x=37
