It can help immensely if you are familiar with the squares and cubes of small integers. Of course, your knowledge of regular times tables will get you to the fact that ...
... 27 = 3·9 = 3·3·3 = 3³
Knowledge of divisibility rules is helpful, too. Here, you can see that 135 ends in 5, so you know that 5 is a factor of the number.
Answer:
Option C.
Step-by-step explanation:
we have
Solve for x
That means ----> Isolate the variable x
Multiply by 8 both sides to remove the fractions
Divide by 5 both sides
Multiply by -1 both sides
Answer:you have to figure out what x is
Step-by-step explanation:
Step-by-step explanation:
the length of unknown side =
√18²-(33-25)² =
√18²-8²= √324-64
=√260 = 16.1 ft
the perimeter= 16.1 +33+18+25
= 92.1 ft
