The temperature seventeen degree below zero degree can be expressed as,

So answer is -17 degrees.
Option A is correct answer.
Answer:
x = 19
Step-by-step explanation:
Trapezium area formula:
, where a & b are the two bases.
Now, if we plug in our known values, we can solve for the missing base.


He answer is d which is 25

The solutions would be +0.37 and -0.37.
When completing the square, we take 1/2 of the value of b (in this case 5). 5/2=2.5. We then square this number: 2.5²=6.25. We add this value to both sides of the equation:
x²+5x+6.25 = 2+6.25
(x+2.5)² = 8.25
Take the square root of both sides:
√(x+2.5)² = √8.25
x + 2.5 = 2.87
Subtract 2.5 from both sides:"
x+2.5-2.5 = 2.87-2.5
x = 0.37
We have to take the positive and negative values for solutions, however, since a square root has both positive and negative answers.
