According to Pythagoras Theorem
H^2= A^2+B^2
B= √64-49= √15
Well, the first slot would be 0.
Second slot would be 1.
So to explain, 0*2=0, so you have O.
2*1=2 so you have H2
Now you have H2O
I hope this helps! (:
Let x = the amount of feet descended in 3 minutes (thus the total change of altitude of the balloon)
320 (feet per minute) / 1 (minute) = x (feet per minute) / 3 (minutes)
1) Divide: 320/1 = 320.
2) Multiply: 320 x 3= 960.
The balloon that descends at a rate of 320 feet/minute (so, every minute, it descends 320 feet) descends a total of 960 feet in 3 minutes.
The balloon's total change in altitude is -960<span>

Answer:
x = , x =
Step-by-step explanation:
The first step is to get rid of the square on the x, and to get rid of it, you square root both sides of the equation, like so:
A perfect square is when a number has two factors that are identical to one another. In this case, 9 and 49 are both perfect squares, meaning we can break them down:
The square root of 9 is 3. (3 · 3 = 9)
The square root of 49 is 7. (7 · 7 = 49)
x =
The answer is also x = because a negative · a negative = a positive.
