x²-48-1 =1-1

x²-49=0 means : x²-7²=0

by identity : a²-b²= (a-b)(a+b)

by factoring: (x-7)(x+7)=0

x-7=0 or x+7=0

saul85 [17]

Answer:

The temperature outside is 75.6°F

Step-by-step explanation:

We are given the following in the question:

The temperature of dry ice = - 109.3°F

Let x be the temperature outside in Fahrenheit.

It is given that the temperature of dry ice is 184.9°F less than the outside temperature.

Thus, we can write the equation:

$x - 184.9 = -109.3$

Solving, the above equation, we get:

$x - 184.9 = -109.3\\x = -109.3 + 184.9\\x = 75.6$

Thus, the temperature outside is 75.6°F
