Answer:
Step-by-step explanation:
<u>We know that:</u>
- -4 + x = 16 [x = difference between two temperatures]
<u>Solution:</u>
- -4 + x = 16
- => x = 16 + 4
- => x = 20
Hence, the difference between the two temperatures is 20°.

Answer:
d. c = 100; (x – 10)²
Step-by-step explanation:
Note that (x+a)²=x²+2ax+a².
In our case, 2a=-20, so 'a' must be -10.
Since c=a², and a=-10, c=(-10²)=100.
Since a=-10, the perfect square is (x – 10)²
