The temperature one cold morning is -5 °C. By noon, the temperature had increased by 3 degrees and at 4 PM the temperature was zero. The increase from noon to 4 PM was

2°C

Step-by-step explanation:

Morning

-5°C

Noon (+3)

-2°C

4pm (+?)

0°C

Equation I used:

(-5) + (3) + x = 0

I'm assuming you're being taught how to work with negative intervals in algebra? Don't worry, that's why you're practising with temperature. Instead of asking online, try using the progress your teacher taught you. If you have notes, look back at them. Practise makes perfect :)

A composite figure is considered composite when it is a combination of 2 or more simpler shapes. From the given pairs in the choices above, the most likely to be a composite figure is either the 1st or 2nd set. Those are (8)(6)(6) + (8)(6)(4) and (8)(6)(10) + (8)(6)(4).
