Answer:

M = -2

Step-by-step explanation:

7 (M + 5) = 21

7M + 35 = 21

7M = 21 - 35

7M = -14

M = -14/7

Find the limit of the function algebraically. limit as x approaches negative 2 of quantity x squared minus four divided by quant

lakkis [162]

ANSWER

The limit is -4

EXPLANATION

$\displaystyle\lim_{x\to -2} \dfrac{x^2-4}{x+2}$

The numerator factors into (x-2)(x+2)

$\displaystyle\lim_{x\to -2} \dfrac{(x-2)(x+2)}{x+2}$

The (x+2) cancel out

$\displaystyle\lim_{x\to -2} (x-2)$

By direct substitution

$\displaystyle\lim_{x\to -2} (x-2) = -2 -2 = -4$
