Answer:
Multiply it by itself one time.
Step-by-step explanation:
For example, if you are trying to find 3 squared, you would do 3*3.
If it's 3 cubed, you do 3*3*3
And so on and so forth
- d is distance, (x_1,y_1) and (x_0,y_0) two points on a coordinate grid.
In our case :
Given,
The carrot comes in pack of 80
Zunchie comes in the pack of 40
The paper comes in the pack of 50.
To find,
The fewest number of each kind of seed that farmer brown will buy.
Solution,
To find least no of each kind, we must take the LCM of the above numbers such that,
The prime factors of the given numbers are :
80 = 2 × 2 × 2 × 2 × 5
40 = 2 × 2 × 2 × 5
50 = 2 × 5 × 5
LCM of 80,40 and 50 = 2 × 2 × 2 × 2 × 5 × 5
= 400
He should buy,
400/80 = 5 carrot seeds
400/40 = 10 zunchie seeds
400/50 = 8 papper seeds.
Answer:
7ab - 5a
Step-by-step explanation:
For addition and subtraction this type of variable we should always keep one thing in mind that, we can only add or subtract only those digits whose variables are the same.
Solving given equation step to step:
(2ab - 5a - 7) - (-5ab - 7)
Opening the bracket first,
⇒ 2ab - 5a - 7 - (- 5ab) - (- 7)
⇒ 2ab - 5a - 7 + 5ab + 7
Now, taking same variables digits together
⇒ (2 + 5)ab - 5a - 7 + 7
⇒ 7ab - 5a - 0
⇒ 7ab - 5a
