Celsius to farenhet

Find Celsius when it's -4 Fahrenheit

Solve formula for area of a trapezoid

A= h(b1+b2)
2

Solve for b1

C = (5/9)( F - 32)

when F = -4
C = (5/9)(-4-32) = -20

To convert Celsius to Fahrenheit, you can use the formula:

°F = (°C * 9/5) + 32

Now, let's plug in the given Fahrenheit value of -4 into the formula and solve for Celsius:

°C = (°F - 32) * 5/9

Let's calculate it step by step:

1. Subtract 32 from -4:
-4 - 32 = -36

2. Multiply the result by 5/9:
-36 * 5/9 = -20

Therefore, -4 Fahrenheit is equivalent to -20 Celsius.
