You count how many places the number is away from 0. try writing it out in an equation it would help
Step-by-step explanation:
n2+5=21
n2 =21-5
n2 = 16
n =16/2=8
All triangles interior angles equal 180
So these 3 angles = 180
When it says to estimate, I always think of doing it by hand to show work. So set it up like this:
96
<u>x 34</u>
So follow it out multiplying across 4*6 and 4*9 carrying over as needed to get it to look like this:
96
<u>x 34</u>
384
Do the same for the 3 to get this:
96
<u>x 34</u>
384
2880
Add 384+2880=3264
Your final answer is 3,264
