Answer:

Step-by-step explanation:

(a - b)² = a² + 2ab + b²

Area of square frame =side²

                                   = (2b - 1)²

                                   = (2b)² - 2*2b * 1 + 1²

                                   = 4b² - 4b + 1

What’s the difference quotient simplified
mihalych1998 [28]

\text{Use}\ (a+b)^3=a^3+3a^2b+3ab^2+b^3\\\\f(x+h)\to\text{exchange x to x + h}\\\\f(x)=x^3+3x\\\\f(x+h)=(x+h)^3+3(x+h)\\\\f(x+h)=x^3+3x^2h+3xh^2+h^3+3x+3h\\\\\dfrac{f(x+h)-f(x)}{h}=\dfrac{x^3+3x^2h+3xh^2+h^3+3x+3h-(x^3-3x)}{h}\\\\=\dfrac{x^3+3x^2h+3xh^2+h^3+3x+3h-x^3-3x}{h}\\\\=\dfrac{(x^3-x^3)+3x^2h+3xh^2+h^3+(3x-3x)+3h}{h}\\\\=\dfrac{3x^2h+3xh^2+h^3+3h}{h}\\\\=\dfrac{h(3x^2+3xh+h^2+3)}{h}\\\\=\boxed{3x^2+3xh+h^2+3}

Whats would the slope of (-3,10),(-5,-4) coordinates be?
valentina_108 [34]

Answer:

The slope is 7.

Step-by-step explanation:

Let the given points are (p, q)= (-3, 10) & (r, s) =(-5, -4).

Then the slope (m) = (s-q)/(r-p)

⇒ m = (-4 -10)/(-5-(-3))

⇒ m = (-14) / (-5 +3)

⇒ m = -14/- 2

⇒m = 7

Hence the slope is m =7 .
