Answer:
7 and 8.
Step-by-step explanation:
When we check out what is √49 and √64, we can see that they equal 7 and 8 respectively. Since √56 is between √49 and √64, we can say that √56 is between 7 and 8.
Hoped this helped.
-k-(-8k)
= -k + 8k (two negatives equal one positive)
= 8k-k (flip it around because of the commutative property)
=7k (basic subtraction)
I really hope that helped :)
Using Pythagoras:
12^2+5^2= 144+25=169
√169= 13
