Answer:

Step-by-step explanation:

1) √2 + 2√2 =  ( 1 + 2 ) √2 = 3*√2   = 3√2

4) √8 + √2 = √2*2*2 + √2 = 2√2 + √2 = ( 2 +1 ) √2 = 3√2

7) 2√5 - √5 = (2 - 1)√5 = 1 √5

10 3√5 - 2√5 = (3 - 2) √5 = 1√5

Answer:

f(x) = 2x(x - 8)

f(x) = 2(x - 2)² - 8

Step-by-step explanation:

Let the equation of the quadratic function is,

f(x) = a(x - h)² + k

Here, (h, k) is the vertex of the function.

From the graph attached,

Vertex of the parabola → (2, -8)

Therefore, equation of the function will be,

f(x) = a(x - 2)² - 8

Since, the graph passes through origin (0, 0),

f(0) = a(0 - 2)² - 8

0 = 4a - 8

a = 2

Equation of the given parabola will be,

f(x) = 2(x - 2)² - 8

      = 2(x² - 4x + 4) - 8

      = 2x² - 8x + 8 - 8

      = 2x² - 8x

      = 2x(x - 8)

Therefore, factored form of the function will be,

f(x) = 2x(x - 8)

I do not understand five through eight please help????????????
bogdanovich [222]
For number 5 the answer is 5/2
number 6 is 23/5
number 7 is 31/9
number 8 is 19

All you do is multiply the denominator by the whole number then the product of that you add that to the numerator and then the sum of that you just put that as your numerator and you keep the same denominator.
