The following pieces of empirical evidence have been collected over the years: Historical trend data show an increase in tempera

bija089 [108]

Answer:

C. It supports the scientific explanation for global warming.

Explanation:

The listed pieces of empirical evidence support the scientific explanation for global warming. Global warming is the long-term heating of Earth's climate, and the increase in levels of carbon dioxide and methane is the reason why glacial ice in the Antarctic and Arctic sea is melting.

These pieces of evidence don't deal with the past of the future. They tell us what is going on right now. Based on them, we could make an assumption about what is going to happen in the future, but there are no predictions here.

Also, this data can be used for science journals and textbooks, but that purpose is not expressed here.

This leaves us with option C as the correct one.

What is the value of x, when x2 + 5 = 21?

djverab [1.8K]

Hey there!

$\bold{x^2+5=21}$
Firstly, subtract by the number $\bold{5}$ on each of your sides
$\bold{x^2+5-5=21-5}$
$\bold{Cancel:5-5}$ because it gives us the result of $\bold{1}$
$\bold{Keep:21-5}$ because it equals: $\bold{16}$
$\bold{x^2=16}$
Nextly, we have to take our square root
$\bold{x=}$ ± $\bold{\sqrt{16}}$
Solve the square root and you have found your answer
$\boxed{\boxed{\bold{Answer:x=4[or]x=-4}}}$ $\bold{\checkmark}$

Good luck on your assignment and enjoy your day!
