Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Starting temperature = - 5°F

Temperature at midday =increase in temperature by 78°F = (starting temperature + 78°F)

Temperature at nightfall = decrease in temperature by 32°F = ( temperature at midday - 32°F)

Temperature at midday:

(-5°F + 78°F) = 73°F

Temperature at nightfall:

(Temperature at midday - 32°F)

(73°F - 32°F) = 41°F

Rút gọn (x-4) (x-3) -x(x+5) +82

WINSTONCH [101]

Answer:

-12x + 94

Step-by-step explanation:

Simplify:

$\left(x-4\right)\left(x-3\right)-x\left(x+5\right)+82$

$=x^2-7x+12-x\left(x+5\right)+82$

$=x^2-7x+12-x^2-5x+82$

$=x^2-x^2-7x-5x+12+82$

$=-7x-5x+12+82$

$=-7x-5x+94$

$=-12x+94$
