So firstly, factor out h on the left side: 
Next, divide both sides by h: 
Lastly, subtract both sides by b and your answer will be 
90^2-54^2=5184
root 5184=72
pr=72
Answer:
36=b^2 or b=the square root of 36
Step-by-step explanation:
The sides of a square are all equal in length. To find the area of a square you can multiply the two sides together. Considering that they are the same length, you can just square one of the side lengths to get your answer. To find a side length you can take the square root of the area.
Answer:
The balance of the account is $1335.6
Step-by-step explanation:
To find the new balance of the account after 212 years, we use simple interest formula to calculate that.
Principal = 450
Rate = 0.35% quarterly = (0.35*4) annually = 1.4% = 1.4 / 100 = 0.014
Reason why the rate was converted from quarterly to annually is because simple interest are calculated annually
T = 212 years
Simple Interest (S.I) = ?
S.I = PRT
S.I = 450 * 0.014 * 212
S.I = $1335.6
The balance of the account after 212 years is $1335.6
It is 4:2
Since it is similar AB is double the size of AB' and BC is double the size of BC'. so 4:2 4 is double the size of 2.
