Step-by-step explanation:

$\displaystyle f'(x) = \lim_{h \to 0} \dfrac{f(x + h) - f(x)}{h}$

$\:\:\:\:\:\displaystyle = \lim_{h \to 0} \dfrac{(x+h)^2 -7 -(x^2 - 7)}{h}$

$\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{(x^2 +2hx + h^2 -7) - (x^2 -7)}{h}$

$\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{2hx + h^2}{h}$

$\:\:\:\:\: \displaystyle= \lim_{h \to 0} (2x +h)$

$\:\:\:\:\: \displaystyle= 2x$

How to solve 4(x+1)-(2x-4)=6 using distributive property PLS HELP! THANK U!! giving BRAINLIEST

Pie

Answer: $x=\Large\boxed{-1}$

Step-by-step explanation:

Given equation

$4(x+1)-(2x-4)=7$

Expand the parenthesis and apply the distributive property

$4\times x+4\times1-2x+4=6$

$4x+4-2x+4=6$

Combine like terms

$4x-2x+4+4=6$

$2x+8=6$

Subtract 8 on both sides

$2x+8-8=6-8$

$2x=-2$

Divide 2 on both sides

$2x\div2=-2\div2$

$x=\Large\boxed{-1}$

Hope this helps!! :)
