Find and simplify the difference quotient for the given function
iren2701 [21]
\dfrac{f(x+h)+f(x)}{h}

Replace f(x) and f(x+h) by using the equation given for the problem.

=\dfrac{(2(x+h)^2-(x+h)-1)-(2x^2-x-1)}{h}

Open all parenthesis

= \dfrac{2x^2+4xh+2h^2-x-h-1-2x^2+x+1}{h}

Factor the h

= \dfrac{h(4x+2h-1)+2x^2-2x^2+1-1+x-x}{h}

Other terms not in the parenthesis cancel each other out

\dfrac{h(4x+2h-1)}{h}

Now, simplify

=4x+2h-1

7. If the area of a square is 64 square centimeters, what's the
Anvisha [2.4K]

Answer:

If you're asking what the perimeter is:

C 32cm

If you're asking what the length of a side is:

A 8cm

Step-by-step explanation:

Area of a square is calculated by length x width.

And all four sides of a square are equal in length.

Area: 8cm×8cm=64cm2

Perimeter: 8cm + 8cm + 8cm + 8cm= 32cm

Another way to find the length of the sides would be to take the square root of 64. I believe that only works with the area of a square though.

√(64)=8
