Which expression you find the length x of a side of a rectangle that has a diagonal of 17 units and a width of 8 units?

x = 15 units

Step-by-step explanation:

The diagonal splits the rectangle into 2 right triangles where the diagonal is the hypotenuse

Using Pythagoras' identity to find x

x² + 8² = 17²

x² + 64 = 289 ( subtract 64 from both sides )

x² = 225 ( take the square root of both sides )

x = = 15 units

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
