The perimeter is 38.4 inches
Answer:
=1.23*10^6
Step-by-step explanation:
We have to calculate
(1.93*10^7 )-(9.7*10^6)
In order to add or subtract two numbers in scientific notation, we have to make sure that the power of exponents in both numbers is same.
We have to reduce the power of 10 in first number from 7 to 6
So,
Step 1:
1.93*10^7=1.93*10*10^6
=10.93*10^6
Now,
Step 2:
=(1.93*10^7 )-(9.7*10^6 )
= 10.93*10^6- 9.7*10^6
Step 3:
=(10.93-9.7)*10^6
=1.23*10^6
I’d say 21 tbh unless the sum is half of the brothers age then it would be 9
If u want to make the shape larger, u will have to multiply it by the scale factor that is greater then 1.
if u want to make the shape smaller, then u will multiply by the scale factor that is between 0 and 1
if the scale factor is 1, then the shapes are congruent
